Add optional second output to var and std (bug #62395)
* scripts/statistics/var.m: Add optional second output containing the mean
used to calculate the variance. Move weight isempty check ahead of vector
dimension isscalar check to avoid triggering incompatability error. Add BISTs
testing second output with different calling options. Add BIST testing empty
value passed as variance weight treated as zero. Add new output behavior to
docstring, and update function definitions to show the primary variable.
* scripts/statistics/std.m: Add passthrough for second output from var when
std called with two outputs. Add BISTs testing second output with different
calling options. Update docstring noting new output behavior.
* etc/NEWS.8.md: Note output changes to var and std under Matlab Compatability.

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). - `integral` can now output a second argument passing the error parameter from the underlying integrator. ### Graphical User Interface ### Graphics backend ### 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. ### Alphabetical list of new functions added in Octave 8 ### 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. 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)
