Two methods can be used for personal test:
method 1
① delete my computer – properties – advanced system settings – environment variables – Blas_ VERSION ;
② right click matlab properties to set compatibility, Windows Vista (service Pack1)getenv('BLAS_VERSION')

Invalid path found

② Running in MATLAB

setenv('BLAS_VERSION','')

Note:
the second method is temporary, which needs to be set every time MATLAB is opened, otherwise an error will still be reported.
