Improve performance of inline functions.
* NEWS.8.md: Announce compatibility and performance improvements.
* scripts/legacy/@inline/inline.m: Add new field "fh" to inline
class which holds an anonymous function handle implementing the
inline function. Rename member variable "numArgs" to "nargs"
to get away from CamelCase.
* scripts/legacy/@inline/feval.m: Re-use existing class member
variable "fh" to execute function rather than creating it every
time feval() is called.
* scripts/legacy/@inline/nargin.m: Update to use class member
variable "nargs" rather than "numArgs".

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). ### 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. ### 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)
