maint: changes to follow Octave coding conventions.
* NEWS.8.md: Wrap lines to 72 chars.
* LSODE-opts.in: Use two spaces after sentence ending period.
* LSODE.cc: Use minimum of two spaces between code and start of comment.
* MemoizedFunction.m: Change copyright date to 2022 since this is the year it
was accepted into core. Don't wrap error() lines to 80 chars. Use newlines
to improve readability of switch statements. Use minimum of two spaces between
code and start of comment.
* del2.m, integral.m, interp1.m, interp2.m, griddata.m, inpolygon.m, waitbar.m,
cubehelix.m, ind2x.m, importdata.m, textread.m, logm.m, lighting.m, shading.m,
xticklabels.m, yticklabels.m, zticklabels.m, colorbar.m, meshc.m, print.m,
__gnuplot_draw_axes__.m, struct2hdl.m, ppval.m, ismember.m, iqr.m: Use a space
between comment character '#' and start of comment. Use hyphen for adjectives
describing dimensions such as "1-D".
* vectorize.m, ode23s.m: Use is_function_handle() instead of "isa (x, "function_handle")"
for clarity and performance.
* clearAllMemoizedCaches.m: Change copyright date to 2022 since this is the
year it was accepted into core. Remove input validation which is done by
interpreter. Use two newlines between end of code and start of BIST tests.
* memoize.m: Change copyright date to 2022 since this is the year it was
accepted into core. Re-wrap documentation to 80 chars. Use
is_function_handle() instead of "isa (x, "function_handle")" for clarity and
performance. Use two newlines between end of code and start of BIST tests.
Use semicolon for assert statements within %!test block. Re-write BIST tests
for input validation.
* __memoize__.m: Change copyright date to 2022 since this is the year it was
accepted into core. Use spaces in for statements to improve readability.
* unique.m: Add FIXME note to commented BIST test
* dec2bin.m: Remove stray newline at end of file.
* triplequad.m: Reduce doubly-commented BIST syntax using "#%!#" to "#%!".
* delaunayn.m: Use input variable names in error() statements. Use minimum of
two spaces between code and start of comment. Use hyphen for describing
dimensions. Use two newlines between end of code and start of BIST tests.
Update BIST tests to pass.

Summary of important user-visible changes for version 8 (yyyy-mm-dd): --------------------------------------------------------------------- ### General improvements - Octave's libraries are now built using symbol visibility by default. That means that less symbols are exported from these libraries. Configure with `--disable-lib-visibility-flags` to export all symbols (as in previous versions). - `filter` is now 5X faster, which also speeds up `deconv`, `fftfilt` and `arma_rnd` by the same amount. - `integral` can now output a second argument passing the error measurement used by the underlying integrator. - `perms` now accepts a second argument "unique" to return only unique permutations for inputs with repeated elements. It is faster and takes less memory to call `perms ('aaaabbbbcccc', "unique")` than to call `unique (perms ('aaaabbbbcccc'), "rows")`. - `quadgk` can now accept the `ArrayValued` input parameter to handle array-valued input functions. - `delaunayn` now has consistent trivial simplex checking and removal for all input dimensions, simplex checking 3D inputs is now vectorized, and >3D simplex checking performance has been improved. Simplexes points are now ordered so they will all have positive outward normal vectors. Input type checking has also been added for improved error handling. ### Graphical User Interface ### Graphics backend - Additional properties have been added to the `figure` graphics object: * `"innerposition"` (equivalent to `"position"`) * `"windowstate"` (not yet implemented) - Legend now features a new property `"itemhitfcn"`, allowing the execution of a callback function when a legend item is clicked. ### Matlab compatibility - `inline` functions now support all Matlab methods. The performance of `inline` functions has also been improved. - `sub2ind` now supports index values outside of the size specified by the subscripts. - `cylinder` now accepts a scalar for the radius argument. - `clock` now has an optional second output `ISDST` which indicates if Daylight Savings Time is in effect for the system's time zone. - `print` now accepts option `-image` to specify the "opengl" renderer and `-vector` to specify the "painters" renderer. - `format` now accepts the option "default", which is equivalent to calling `format` without any options to reset the default state. - `quadgk` now stops iterating when `error <= tolerance` while the previous condition was `error < tolerance`. - `var` and `std` now optionally output a second argument containing the mean or weighted mean. - `integral` can now accept the 'ArrayValued' option in combination with 'RelTol' and 'WayPoints'. - The default state for certain graphics properties has been made consistent with Matlab. Object | Property | Default State ------------|------------------|------------ `figure` | `"dockcontrols"` | `"on"` ### Alphabetical list of new functions added in Octave 8 * `clearAllMemoizedCaches` * `matlab.lang.MemoizedFunction` * `memoize` * `pagectranspose` * `pagetranspose` * `uifigure` ### Deprecated functions, properties, and operators The following functions and properties have been deprecated in Octave 8 and will be removed from Octave 10 (or whatever version is the second major release after 8): - Functions Function | Replacement -----------------------|------------------ `shift` | `circshift` `sparse_auto_mutate` | none (see below) - The `sparse_auto_mutate` function no longer has any effect on Octave's behavior. Previously, after calling `sparse_auto_mutate (true)`, Octave would automatically convert sparse matrices to full when a sparse matrix required more memory than simply using full matrix storage. This setting was `false` by default for compatibility with Matlab. Now you must manually convert to full storage when desired. - Properties The following property names are discouraged, but there is no fixed date for their removal. Object | Property | Replacement -----------------|-------------|------------ `uimenu` | `label` | `text` `uimenu` | `callback` | `menuselectedfcn` The following functions were deprecated in Octave 6 and have been removed from Octave 8. - Functions Function | Replacement -----------------------|------------------ `runtests` | `oruntests` - The environment variable used by `mkoctfile` for linker flags is now `LDFLAGS` rather than `LFLAGS`. `LFLAGS` was deprecated in Octave 6, and will be removed in a future version of Octave. ### Old release news - [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)
