MATLAB: What is blas loading error

blas loading errormkl_custom.dll

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."

Best Answer

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.
