Detailed Description

Return the following matrix-vector products, using the vector x and triangular matrix A or its transpose:

\begin{equation} x\leftarrow A-1 x x\leftarrow A^-T x x\leftarrow A^-H x \end{equation}

This generic interface offers a compile-time resolution to the BLAS strsv, dtrsv, ctrsv, ztrsv matrix multiplication routines.
See the documentation of reference BLAS library for the definition of the input arguments.
