Re: Instructions for Installing BLAS and LAPACK library on Octave 5.2.0

Hi Nicholas,

Thanks for your email.

Is it an openblas library which enables the multithreading is inbuilt with
octave ?

If so, please clarify which dll file(librefblas.dll or libopenblas.dll )
needs to be pasted where. If this is not the case, let me know what to do
for the multithreading to work.

finally, after implementing the multithreading feature. how to check it
whether it's implemented or not ?

Many thanks
Ilaya bharathi
