Quantlet: cmatmul
Description: Computes the complex matrix multiplication of X and Y

Usage: z = cmatmul (x, y)
Input:
x complex matrix X
y complexr matrix Y
Output:
z complex matrix

Example:

library("math")

x = complex (#(-2, 0)~#(-1, -2), #(-1, 0)~#(-3, -1))

y = complex (#(-2, -1)~#(-1, 0), #(-1, 0)~#(0, 0))

cmatmul (x, y)

Result:

Contents of z.re

[1,]        4        2 

[2,]        2        0 

Contents of z.im

[1,]        7        1
