Description

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

Parameters

Each of the functions takes the following arguments:

min

Pointer to the first element with the minimum 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.
