Expand description

Matrix–vector product y := op(A) · x.

op(A) is m×n; a holds op==No ? m×n : n×m (always m*n elements), x is length n, y is length m (overwritten). Zero-heap; the dynamic analogue of super::Matrix4x4::multiply_vector, and the shape the GPU coop_gemv decode kernel computes per output row.
