Some vendors of scientific libraries include F90 modules as part of the package. For example, on IRIX, with the SCSL library, one could write: USE SCSL_BLAS This provides explicit interfaces for the BLAS routines, so they can be checked. (Unfortunately we never got around to doing the rest of LAPACK.) Intels MKL has similar with USE MKL95_BLAS. With this you can use things like 'CALL GEMM', and thanks to the generic interfaces the compiler will choose the correct variant based on what args you pass to it. There is also lapack95 from netlib.org: http://www.netlib.org/lapack95/ (Intels MKL lib includes lapack95. No doubt others do to.) W.

Learn what you don't." I have recently started developing a (yet another!) Fortran 95 interface to BLAS and LAPACK. It has (IMHO) some advantages over the alternatives freely available on the web, at least it suits my needs better. However, it is still too fresh to be reliable. You can check it out at http://www.highegg.matfyz.cz/blap95/ Jaroslav

After searching a bit through the docs, I think this is the information that I needed (including 2 examples): http://www.netlib.org/lapack95/lug95/node51.html Thanks, Bart -- "Share what you know.
