DESCRIPTION
Each of these functions computes the average of the first source matrix and the second source matrix and writes the output to the destina-
tion matrix.
It uses the following equation:
z[i] = (x[i] + y[i] + 1) / 2
where i = 0, 1, ..., (m*n - 1) for real data; i = 0, 1, ..., (m*n*2 - 1) for complex data.
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 matrices.
n Number of columns in the matrices.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
