DESCRIPTION

       Each of these functions finds the first element with the minimum magnitude in a complex vector, 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 vector.

       n	       Number of elements in the source vector.

RETURN VALUES

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