Description

The routine performs a simple matrix-matrix multiplication of the form

C = A*B,

where A is m-by-n and complex, B is n-by-n and real, C is m-by-n and complex.

Input Parameters

m

INTEGER. The number of rows of the matrix A and of the matrix C (m 0).

n

INTEGER. The number of columns and rows of the matrix B and the number of columns of the matrix C

(n 0).
