Summary of important user-visible changes for version 9 (yyyy-mm-dd): --------------------------------------------------------------------- ### General improvements - `oruntests`: The current directory now changes to the directory containing the files with the tests for the duration of the test. This aligns the behavior of this function with Octave's test suite. This also means that the file encoding specified in the `.oct-config` file for the respective directory is taken into account for the tests. - `dec2base`, `dec2bin`, and `dec2hex` have all been overhauled. All three functions now accommodate negative inputs and fractional inputs, and repeated code between the functions has been reduced or eliminated. Previously only `dec2bin` and `dec2hex` accepted negative inputs but `dec2base` did not, and none of the three accepted fractional inputs. But now, `dec2base (100*pi, 16, 4, 6)` for exampele returns a base-16 string with four places for the integer part and six places for the fractional part. Omitting the number of decimal places (the fourth input) retains old behavior for backward compatibility, except that non-integer inputs will no longer error. - `quiver` and `quiver3` now properly plot non-float numeric inputs by internally recasting them to 'double' (bug #59695). Both functions now honor a previously ignored scaling factor input when there is only a single arrow (bug #39552), and `quiver3` no longer produces an error when a scaling factor is input without x and y inputs. Both functions now also accept a scale factor of "off" which is equivalent to setting it to 0. When a linestyle with a base marker is set suppressing arrowhead display, subsequent name-value property pairs in the quiver/quiver3 function call will no longer turn arrowhead display back on (bug #64143). The linewdith property now also affect the line width of the base marker. - The `inputParser` function has been re-architected for a 60% performance improvement. ### Graphical User Interface ### Graphics backend * The `set` function now accepts any combination of name/value pairs, cell array of names / cell array of values, or property structures. This change is Matlab-compatible. * When the `hold` function is used without arguments to toggle the current state the resulting value is now displayed in the Command Window for informational purposes. ### Matlab compatibility - The `inputParser` function now implements the `PartialMatching` property for `Parameter` and `Switch` names. For Matlab compatibility, `PartialMatching` is now set to true by default which may change the behavior of existing code. - Overhauled `mean`, `median`, `var`, and `std` functions have been imported from statistics package v1.5.4 to compatibly implement 'nanflag' (bug #50571), 'all' (bug #58116), and 'vecdim' (bug #58089) options, preserve output class, and match expected output behavior for empty (bug #50583) and sparse inputs (bug #63291). Both `median` and `mean` can handle large int values without overflow or precision concerns (bug #54567), and `mean` avoids errors due to limits of single precision by processing as doubles (bug #63848). `median` has also adopted the 'outtype' option from `mean`. - `mad` function now produces Matlab compatible output using improved `mean` and `median` functions. 'vecdim' and 'all' options are now supported. `mad` ignores all NaN values (using 'omitnan' mean/median option) and produces expected output behavior for empty inputs. - `mode` now produces Matlab compatible output for empty inputs (bug #50583). - `normalize` now produces Matlab compatible output for inputs containing NaN values (bug #50571). - `cov` now processes the input form cov(x,y) with two separate data arrays x and y, as cov(x(:),y(:)) to maintain Matlab compatibility. It also accepts a NANFLAG option to allow ignoring NaN entries in input data (bug #50571) and produces Matlab compatible outputs for empty inputs (bug #50583). `corr` and `corrcoef` internal code has been adapted to the new `cov` behavior with no change to user interface. Packages using the octave core's `cov` that rely on the previous calling form may need to make similar adaptations. Calls for cov(x) with a vector x expecting a scalar return can get the previous results from `cov(x)(2)`, and calls to cov(x,y) with x and y matrices expecting columnwise covariance calculation can obtain the previous results using `cov([x,y])(1:nx, nx+1:end)`, where nx = columns(x). - `qz` now handles input and output arguments in a Matlab compatible way. It always computes the complex QZ decomposition if there are only two input arguments, and it accepts an optional third input argument 'real' or 'complex' to select the type of decomposition. The output arguments are always in the same order independently of the input arguments, and the generalized eigenvalues are no longer returned (one can use the `ordeig` function for that purpose). The optional reordering of the generalized eigenvalues has been removed (one can use the `ordqz` function for that purpose). ### Alphabetical list of new functions added in Octave 9 * `isuniform` * `tensorprod` ### Deprecated functions, properties, and operators The following functions and properties have been deprecated in Octave 9 and will be removed from Octave 11 (or whatever version is the second major release after 9): - Functions Function | Replacement -----------------------|------------------ - Properties The following property names are discouraged, but there is no fixed date for their removal. Object | Property | Replacement -----------------|-------------|------------ - Core * The `idx_vector::bool()` function is obsolete and always returns true. Any uses can simply be removed from existing code with no loss of function. * The `all_ok(const Array<octave::idx_vector>&)` function in `Array-util.h` is obsolete and always returns true. Any uses can simply be removed from existing code with no loss of function. * The member variable `octave_base_value::count` is deprecated and will be removed from Octave 11. Replace all instances with the new name `m_count`. The following features were deprecated in Octave 7 and have been removed from Octave 9. - Functions Function | Replacement ---------------------------|------------------ disable_diagonal_matrix | optimize_diagonal_matrix disable_permutation_matrix | optimize_permutation_matrix disable_range | optimize_range - Operators Operator | Replacement ---------|------------ .+ | + .+= | += .- | - .-= | -= ** | ^ **= | ^= .** | .^ .**= | .^= - Interpreter * The use of `'...'` for line continuations *inside* double-quoted strings has been removed. Use `'\'` for line continuations inside strings instead. * The use of `'\'` as a line continuation *outside* of double-quoted strings has been removed. Use `'...'` for line continuations instead. * Support for trailing whitespace after a `'\'` line continuation has been removed. Delete unnecessary trailing whitespace. - For plot functions, the use of numbers to select line colors in shorthand formats was an undocumented feature that was removed in Octave 9. - The environment variable used by `mkoctfile` for linker flags is now `LDFLAGS` rather than `LFLAGS`. `LFLAGS` was deprecated in Octave 6 and has been removed. Summary of bugs fixed for version 9.1.0 (yyyy-mm-dd): ---------------------------------------------------- - Bugfixes to `whos -file`, `urlread`, `mat2cell`, `set`. - Memory usage reduced for `movfun` by eliminating temporary copies. - Memory usage reduced when saving to file, preventing OOM and data loss. - Several race conditions removed in signal handler. - Performance improvements: avoid unnecessary string construction, use static casts instead of dynamic casts where possible. ### Old release news - [Octave 8.x](etc/NEWS.8) - [Octave 7.x](etc/NEWS.7) - [Octave 6.x](etc/NEWS.6) - [Octave 5.x](etc/NEWS.5) - [Octave 4.x](etc/NEWS.4) - [Octave 3.x](etc/NEWS.3) - [Octave 2.x](etc/NEWS.2) - [Octave 1.x](etc/NEWS.1)
