title: How to perform Vector-Matrix Multiplication with BLAS ?
body: <p>BLAS defines the GEMV (Matrix-Vector Multiplication) level-2 operation. How to use a BLAS Library to perform Vector-Matrix Multiplication ? </p>
  
  <p>It's probably obvious, but I don't see how to use BLAS operation for this multiplication. I would have expected a GEVM operation. </p>
