Function ndarray::linalg::general_mat_mul

pub fn general_mat_mul<A, S1, S2, S3>(alpha: A,
                                      a: &ArrayBase<S1, Ix2>,
                                      b: &ArrayBase<S2, Ix2>,

General matrix multiplication.

Compute C ← α A B + β C

The array shapes must agree in the way that if a is M × N, then b is N × K and c is M × K.

Panics if array shapes are not compatible
