- Template Parameters
T – Floating point precision type.
- Parameters
mat – Complex data array repr. a flatten (row-wise) matrix m * n.
v_in – Complex data array repr. a vector of shape n * 1.
v_out – Pre-allocated complex data array to store the result.
m – Number of rows of
mat.n – Number of columns of
mat.transpose – Whether use a transposed version of
m_right.
