 in the global namespace (See also subfunctions and private functions).
 In addition, variables in the enclosing function are visible within the
 nested function.  This makes it possible to have a pseudo-global variable
 which can be seen by a group of functions, but which is not visible in
 the global namespace.
 Example:
 function outerfunc (...)
 ...
 function nested1 (...)
 ...
 will be consistent with other binary operators.
 ** Redundant terminal comma accepted by parser
 A redundant terminal comma is now accepted in matrix
 definitions which allows writing code such as
 [a,...
 b,...
 c,...
 ] = deal (1,2,3)
 ** 'emptymatch', 'noemptymatch' options added to regular expressions.
 With this addition Octave now accepts the entire set of Matlab options
 for regular expressions.  'noemptymatch' is the default, but 'emptymatch'
 has certain uses where you need to match an assertion rather than actual
 characters.  For example,
 regexprep ('World', '^', 'Hello ', 'emptymatch')
 => Hello World
 where the pattern is actually the assertion '^' or start-of-line.
 ** For compatibility with Matlab, the regexp, regexpi, and regexprep
 functions now process backslash escape sequences in single-quoted pattern
 strings.  In addition, the regexprep function now processes backslash
 escapes in single-quoted replacement strings.  For example,
 regexprep (str, '\t', '\n')
 would search the variable str for a TAB character (escape sequence \t)
 and replace it with a NEWLINE (escape sequence \n).  Previously the
 expression would have searched for a literal '\' followed by 't' and

 month, and year.  This may produce changes in existing scripts.
 ** The error function and its derivatives has been extended to accept complex
 arguments.  The following functions now accept complex inputs:
 erf  erfc  erfcx
 In addition two new error functions erfi (imaginary error function) and
 dawson (scaled imaginary error function) have been added.
 ** The glpk function has been modified to reflect changes in the GLPK
 library.  The "round" and "itcnt" options have been removed.  The
 "relax" option has been replaced by the "rtest" option.  The numeric
 values of error codes and of some options have also changed.
 ** The kurtosis function has changed definition to be compatible with
 Matlab.  It now returns the base kurtosis instead of the "excess kurtosis".
 The old behavior can be had by changing scripts to normalize with -3.
 "excess kurtosis" = kurtosis (x) - 3
 ** The moment function has changed definition to be compatible with
 Matlab.  It now returns the central moment instead of the raw moment.
 The old behavior can be had by passing the type argument "r" for raw.
 ** The default name of the Octave crash dump file is now
 "octave-workspace" instead of "octave-core".  The exact name can
 always be customized with the octave_core_file_name function.
 ** A citation command has been added to display information on how to
 cite Octave and packages in publications.  The package system will

 Summary of important user-visible changes for version 3.4.3:
 -----------------------------------------------------------
 ** Octave 3.4.3 is a bug fixing release.
 Summary of important user-visible changes for version 3.4.2:
 -----------------------------------------------------------
 ** Octave 3.4.2 fixes some minor installation problems that affected
 version 3.4.1.
 ---------------------------------------------------------
 ** BLAS and LAPACK libraries are now required to build Octave.  The
 subset of the reference BLAS and LAPACK libraries has been removed
 from the Octave sources.
 ** The ARPACK library is now distributed with Octave so it no longer
 needs to be available as an external dependency when building
 Octave.
 ** The `lookup' function was extended to be more useful for
 ** The built-in function equivalents to associative operators (`plus',
 `times', `mtimes', `and', and `or') have been extended to accept
 multiple arguments.  This is especially useful for summing
 (multiplying, etc.) lists of objects (of possibly distinct types):
 matrix_sum = plus (matrix_list{:});
 ** An FTP object type based on libcurl has been implemented.  These
 objects allow ftp connections, downloads and uploads to be
 managed.  For example,
 assert (zeros (0, 0), [])
 assert (2*ones (1, 5), (2) (ones (1,5)))
 ** The behavior of library functions `ismatrix', `issquare', and
 `issymmetric' has been changed for better consistency.
 * The `ismatrix' function now returns true for all numeric,
 logical and character 2-D or N-D matrices.  Previously, `ismatrix'
 returned false if the first or second dimension was zero.
 Hence, `ismatrix ([])' was false,
 while `ismatrix (zeros (1,2,0))' was true.
 * The `issquare' function now returns a logical scalar, and is
 equivalent to the expression
 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x)
 The dimension is no longer returned.  As a result, `issquare ([])'
 now yields true.
 * The `issymmetric' function now checks for symmetry instead of
 Hermitianness.  For the latter, ishermitian was created.  Also,
 logical scalar is returned rather than the dimension, so
 `issymmetric ([])' is now true.
 ** Function handles are now aware of overloaded functions.  If a
 function is overloaded, the handle determines at the time of its
 reference which function to call.  A non-overloaded version does not
 need to exist.
 ** The operation-assignment operators +=, -=, *= and /= now behave more
 efficiently in certain cases.  For instance, if M is a matrix and S a
 scalar, then the statement
 M += S;
 will operate on M's data in-place if it is not shared by another
 variable, usually increasing both time and memory efficiency.
 Only selected common combinations are affected, namely:
 matrix += matrix
 matrix -= matrix
 matrix .*= matrix
 matrix ./= matrix
 ** Octave now allows user-defined `subsasgn' methods to optimize out
 redundant copies.  For more information, see the manual.
 ** More efficient matrix division handling.  Octave is now able to
 handle the expressions
 M' \ V
 M.' \ V
 V / M
 (M is a matrix and V is a vector) more efficiently in certain cases.
 In particular, if M is triangular, all three expressions will be
 handled by a single call to xTRTRS (from LAPACK), with appropriate
 flags.  Previously, all three expressions required a physical
 transpose of M.
 ** More efficient handling of certain mixed real-complex matrix
 operations.  For instance, if RM is a real matrix and CM a complex
 matrix,
 RM * CM
 can now be evaluated either as
 complex (RM * real (CM), RM * imag (CM))
 ** 'str2double' now has a compiled implementation and the API conforms
 to Matlab.  The additional Octave-specific features of returning a
 boolean matrix indicating which elements were successfully converted
 has been removed.
 ** Matlab-style ignoring input and output function arguments using
 tilde (~) is now supported.  Ignored output arguments may be
 detected from a function using the built-in function `isargout'.
 For more details, consult the manual.
 ** The list datatype, deprecated since the introduction of cells, has
 been removed.
 ** The accumarray function has been optimized and is now significantly
 longer always equal in Octave.  Octave may also produce a matrix
 with nnz < nzmax as a result of other operations, so you should
 consistently use nnz unless you really want to use nzmax (i.e., the
 space allocated for nonzero elements).
 Sparse concatenation is also affected, and concatenating sparse
 matrices, especially larger collections, is now significantly more
 efficient.  This applies to both the [] operator and the
 cat/vertcat/horzcat functions.
 ** It is now possible to optionally employ the xGESDD LAPACK drivers
 for computing the singular value decomposition using svd, instead
 of the default xGESVD, using the configuration pseudo-variable
 svd_driver.  The xGESDD driver can be up to 6x times faster when
 singular vectors are requested, but is reported to be somewhat less
 robust on highly ill-conditioned matrices.
 ** Configuration pseudo-variables, such as page_screen_output or
 confirm_recursive_rmdir (or the above mentioned svd_driver), now
 accept a "local" option as second argument, requesting the change
 to be undone when the current function returns:
 function [status, msg] = rm_rf (dir)
 confirm_recursive_rmdir (false, "local");
 [status, msg] = rmdir (dir, "s");
 ...
 endfunction
 Upon return, confirm_recursive_rmdir will be restored to the value
 it had on entry to the function, even if there were subsequent
 changes to the variable in function rm_rf or any of the functions
 it calls.
 ** pkg now accepts a -forge option for downloading and installing
 packages from Octave Forge automatically.  For example,
 pkg install -forge general
 will automatically download the latest release of the general
 package and attempt to install it.  No automatic resolving of
 dependencies is provided.  Further,
 pkg list -forge
 can be used to list all available packages.
 ** The internal data representation of structs has been completely
 rewritten to make certain optimizations feasible.  The field data
 can now be shared between structs with equal keys but different
 ** The following functions are new in Octave 3.4:
 accumdim    erfcx        nfields      pqpnonneg  uigetdir
 bitpack     fileread     nth_element  quadcc     uigetfile
 bitunpack   fminbnd      onCleanup    randi      uiputfile
 blkmm       fskipl       pbaspect     repelems   uimenu
 cbrt        ifelse       pie3         reset      whitebg
 curl        ishermitian  powerset     rsf2csf
 chop        isindex      ppder        saveas
 daspect     luupdate     ppint        strread
 divergence  merge        ppjumps      textread
 ** Using the image function to view images with external programs such
 as display, xv, and xloadimage is no longer supported.  The
 image_viewer function has also been removed.
 a = 1;
 a.x = 2;
 This is no longer possible unless a is an empty matrix or cell
 array.
 ** The dlmread function has been extended to allow specifying a custom
 value for empty fields.
 ** The dlmread and dlmwrite functions have been modified to accept
 file IDs (as returned by fopen) in addition to file names.
 ** Octave can now optimize away the interpreter overhead of an
 anonymous function handle, if the function simply calls another
 function or handle with some of its parameters bound to certain
 values.  Example:
 f = @(x) sum (x, 1);
 When f is called, the call is forwarded to @sum with the constant 1
 appended, and the anonymous function call does not occur on the
 call stack.
 ** Deprecated functions.

 removed from Octave 3.4.

 ** New experimental OpenGL/FLTK based plotting system.
 An experimental plotting system based on OpenGL and the FLTK
 Octave will now attempt to share data in some cases where previously
 a copy would be made, such as certain array slicing operations or
 conversions between cells, structs and cs-lists.  This usually reduces
 both time and memory consumption.
 Also, Octave will now attempt to detect and optimize usage of a vector
 as a stack, when elements are being repeatedly inserted at/removed from
 the end of the vector.
 ** Improved performance for reduction operations.
 The performance of the sum, prod, sumsq, cumsum, cumprod, any, all,
 max and min functions has been significantly improved.
 ** Sorting and searching.
 The performance of sort has been improved, especially when sorting
 indices are requested.  An efficient built-in issorted
 implementation was added.  The sortrows function now uses a more
 efficient algorithm, especially in the homogeneous case.  The lookup
 function is now a built-in function performing a binary search,
