    alpha: A,
    a: &ArrayBase<S1, Ix2>,

General matrix-vector multiplication.

Compute y ← α A x + β y

where A is a M × N matrix and x is an N-element column vector and y an M-element column vector (one dimensional arrays).

Panics if array shapes are not compatible
Note: If enabled, uses blas gemv for elements of f32, f64 when memory layout allows.
