How can I use the AMD Optimizing CPU Libraries (AOCL) with MATLAB for windows?

My CPU is amd 9900X3D, GPU is RTX5070, Windows11 25H2

To use the AMD optimization in MATLAB, I have already see the Q&A for this link:'How can I use the BLAS and LAPACK implementations included in AMD Optimizing CPU Libraries (AOCL) with MATLAB R2022a? - MATLAB Answers - MATLAB Central'

Then I install the AOCL5.0 in this link:'AMD Optimizing CPU Libraries EULA 5.1'

Follow the tutorial in the text，I found matlab error:

-----------------------------------------------------------------------------------------------

version -blas, version -lapack

BLAS: trying environment BLAS_VERSION...

BLAS: loading AOCL-LibBlis-Win-MT-dll.dll

BLAS: unloading libraries

错误使用 matlab.lang.internal.versionPlugins.blas

BLAS 加载错误:

AOCL-LibBlis-Win-MT-dll.dll: 找不到指定的模块。

--------------------------------------------------------------

Is this because my OS is Windows? and how to solve it?

Thank u

Approximate translation:

Error using matlab.lang.internal.versionPlugins.blas

BLAS loading error:

AOCL-LibBlis-Win-MT-dll.dll: The specified module could not be found.

I know the meaning of this error, and I also try to addpath to the windows environments, but this not work.

Hi 瑛杰

A few possible reasons for this error can be:

1) MATLAB may not be able to find, load, or recognize the AOCL DLL files, or there may be naming conflicts.

2) The environment variables or library paths may not be set correctly, causing MATLAB to fail to load the required DLLs.

are only valid for the AOCL version that is shipping with MATLAB.

As @Ayush pointed out, if you install AOCL yourself, you need to specify the entire path to the binaries:

BLAS_VERSION=\full\path\to\lib\blasLib.dll

And same for LAPACK_VERSION.

Also, notice that arbitrary AOCL installs might not be suited to be used with MATLAB and have not been qualified on our end.
