Detailed Description

General Matrix-Vector-Multiplication.

GEMV performs one of the matrix-vector operations

\[\vy = \alpha\cdot\mA\cdot\vx + \beta*\vy\ \ \text{ or }\ \ \vy = \alpha\cdot\mA^\top\cdot\vx + \beta*\vy\]

where \(\alpha\) and \(\beta\) are scalars, \(\vx\) and \(\vy\) are vectors and \(\mA\) is an \(m \times n\) matrix.
