What is blas loading error?

I am trying to use matrix algebra functions in matlab but I am getting BLAS loading error. It gives error like:"Error using norm BLAS loading error: mkl_custom.dll: The specified module could not be found."

@KRUPAL PATEL: please show use the code that causes this error, and also the full error message (this means all of the red text).

It might be the case that the Environment Variables 'BLAS_VERSION' is defined and it make MATLAB to use whatever the library specified by 'BLAS_VERSION'. If the specified library does not exist, you get an error :"Error using norm BLAS loading error: mkl_custom.dll: The specified module could not be found."

You can check if the variable is defined by executing the following command on MATLAB

 getenv('BLAS_VERSION')

If the result is some library that you are not aware of, you can just delete it and restart MATLAB to see if the issue is resolved.

Hi Kruptal,

A BLAS Loading error can occur when the mkl.dll file for the corresponding function that you are using is corrupted. Replacing the mkl.dll file with a working version or re=installing MATLAB may resolve your issue.
