n*M.V ( alpha A x -- alpha*A.x )
Basic Linear Algebra Subroutines (BLAS) interface » BLAS interface matrix operations

Prev:n*M.V+n*V ( alpha A x beta y -- alpha*A.x+b*y )
Next:M.V ( A x -- A.x )


Vocabulary
math.blas.matrices

Inputs
alphaa number
Aa blas-matrix-base
xa blas-vector-base


Outputs
alpha*A.xa blas-vector-base


Word description
Calculate the matrix-vector product αAx and return a freshly allocated vector containing the result. The width of A must match the length of x. The length of the returned vector will match the height of A. Corresponds to the xGEMV routines in BLAS.
