These correspond in the following way to the BLAS symbols: :trans = CblasTrans :notrans = CblasNoTrans :conjtrans = CblasConjTrans. That is, transpose, no transpose, conjugate transpose. Look at the BLAS documentation for more information; unfortunately, the GSL BLAS documentation like http://www.gnu.org/s/gsl/manual/html_node/Level-2-GSL-BLAS-Interface.htmldoe... really explain this much. In other words, the GSLL documentation is weak, just like the GSL documentation is :-) If you just want a regular product, use :notrans (no transpose of the matrix before multiplying), which is the default.

Hello all, I'm unable to find out how to use the :trans, :notrans, and :conjtrans keywords when using the matrix-product function. Could someone help me out with this?
Thanks
