DESCRIPTION
Each of these functions performs matrix multiplication of the first matrix to the second matrix or the first complex matrix to the second
complex matrix.
For real data, the following equation is used:
l-1
z[i*n + j] = SUM (x[i*l + k] * y[k*n + j])
k=0
where i = 0, 1, ..., (m - 1); j = 0, 1, ..., (n - 1).
For complex data, the following equation is used:
l-1
z[2*(i*n + j)] = SUM (xR*yR - xI*yI)
k=0
l-1
z[2*(i*n + j) + 1] = SUM (xR*yI + xI*yR)
k=0
where
xR = x[2*(i*l + k)]
xI = x[2*(i*l + k) + 1]
yR = y[2*(k*n + j)]
yI = y[2*(k*n + j) + 1]
i = 0, 1, ..., (m - 1)
j = 0, 1, ..., (n - 1)
PARAMETERS
Each of the functions takes the following arguments:
z Pointer to the destination matrix.
x Pointer to the first source matrix.
y Pointer to the second source matrix.
m Number of rows in the first matrix.
l Number of columns in the first matrix, and number of rows in the second matrix.
n Number of columns in the second matrix.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
