Tell me the matrix multiplication function in the GSL library. I searched a lot, but I can’t fix it. If anyone knows about this feature, answer. Thanks in advance.
I think you will want to use the gemm family of functions, for example gsl_blas_sgemm() . Just set the scalars to one, and the added matrix to zero. An example is here .
gemm
gsl_blas_sgemm()
