Fix bug and New funcs

Adding New functions

• Blas::getParallel()
• Blas::rotm()
• Blas::rotmg()

Packaging

• Changed deb package information not to be limited to Ubuntu

Bug fixes

• Fixed the issue where ReduceSum's float64 did not work.

Warning error removal

• Warning error removal on Windows

Name based binding on Windows etc.

Major changes:

• Changed OpenBLAS DLL calls to name-based dynamic calls on Windows. This allows it to work even if the OpenBLAS DLL version changes.
• Switched the functionality of the Math class to Rindow-Matlib.
• On Windows, OpenMP is used in the Rindow-Matlib functions, so it runs multi-threaded.
• On Linux, OpenMP cannot be used in PHP, so it runs single-threaded.

New functions:

• notEqual, not, transpose, bandpart, omatcopy

incompatible functions:

• pow
• searchsorted

Refine compare functions and PHP8.1(and 8.2) support

Changed the interface of comparison functions.
And it supports PHP 8.1.

(Added pre-built version of php8.2. If you can't find the binary you're looking for, click "Show all xxx assets". Jan.28.2023)

New feature:

• NaN and INF supports. Various functions now work with NaN and INF numbers in mind.
• Add newfunctions: nam2num(), isnan(), searchsorted(), cumsum(), sin(), cos(), tan(), greatorEqual(), lessEqual()

Backwards incompatible interface changes:

• maximum(), minimum(), greator(), less(), pow(), imagecopy()

PHP8.1 support

• Changed the interface type declaration in PHP8.0 and above so that there is no warning about the type declaration.

Known issues:

• When building on Ubuntu 202204, the phpize and the configure shows some warnings.

• Math::selectAxis1()
• Math::scatterAxis0()
• Math::scatterAxis1()

New functions

• Math::gather()
• Math::reduceGather()
• Math::repeat()
• Math::imagecopy()

Change interface of the Math slice functions

Math slice functions supports axis 2.

• Math::slice()

PHP8 compatible

PHP8 compatible
The format of LinearBuffer has changed, so please update all dependent PHP extensions.

LinearBuffer interface support

interop-phpobjects LinearBuffer support.

All functionality has changed to use the LinerBuffer interface of interop-phpobjects.

All functions accept not only OpenBLAS native Buffer objects, but also Buffer objects that implement the LinearBuffer interface. This means that native Buffer objects will not be accepted as-is and you will need to create a subclass that implements Interop \ Polite \ Math \ Matrix \ LinearBuffer in Interop-objects.

Add BLAS Level3 functions

• symm
• syrk
• syr2k
• trmm
• trsm

New Pre-buildbinaries

The format of pre-built binaries has been renewed, and the Windows version now uses the OpenBLAS library of external DLLs when running. Please download the OpenBLAS DLL from the OpenBLAS release page in the binary of the corresponding release.

Download it from the "Asset" link on this page.
