The prototypes for the low-level CBLAS functions are declared in the file gsl_cblas.h. For the definition of the functions consult the documentation available from. This article shows how to use cblas (and others) in C with a simple example: To test the BLAS routines we want to perform a simple matrix-vector multiplication . Gentoo package sci-libs/cblas-reference: C wrapper interface to the F77 reference BLAS implementation in the Gentoo Packages Database.
