Description

Each of these functions finds the first element with the maximum magnitude in a complex matrix, then puts the real and imaginary parts of it into max[0] and max[1], respectively.

Parameters

Each of the functions takes the following arguments:

max

Pointer to the first element with the maximum magnitude

x

Pointer to the first element of the source matrix.

m

Number of rows in the source matrix

n

Number of columns in the source matrix

Return Values

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
