How to use recent AMD AOCL version in Matlab2025b (windows)

I have download and installed AMD AOCL (2025 version) from official amd website and its currently in my Program Files folder. followed guides from ( https://www.mathworks.com/matlabcentral/answers/1672304-how-can-i-use-the-blas-and-lapack-implementations-included-in-amd-optimizing-cpu-libraries-aocl-wi ) this link, which is to run

> set BLAS_VERSION=AOCL-LibBlis-Win-MT-dll.dll

> set LAPACK_VERSION=AOCL-LibFLAME-Win-MT-dll.dll

When i start Matlab this way, and check version, it is a

What were you expecting instead?

@Walter Roberson, I presume @Xinyu was expecting a 2025 build date from the question preliminaries.

@Xinyu, the instructions you followed simply told how to reference the version shipped with MATLAB; not another version. You would need to set the two environment variables to point at the newly-installed versions instead and that may well not work as what is expected by MATLAB may not be able to be changed.

A risky attempt would be to replace the present dll's in those locations with the new ones, probably having to rename them to match.

@dpb: Replacing the existing DLLs with the new ones caused MATLAB to crash for me.

@Walter Roberson and @Xinyu: It would be great if MathWorks could either ship new MATLAB releases with up-to-date AMD AOCL builds, or provide guidance on how users can safely replace the shipped version with the latest one. In my experience, AMD AOCL delivers substantial speedups - even with the slightly outdated 2023 build included in MATLAB. I submitted a feature request; @Xinyu, you might consider doing the same.

Not surprising; as noted it was a risk with a low likelihood of success.
