SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_MatrixUnit_U8(mlib_u8 *z, mlib_s32 n);

       mlib_status mlib_MatrixUnit_U8C(mlib_u8 *z, mlib_s32 n);

       mlib_status mlib_MatrixUnit_S8(mlib_s8 *z, mlib_s32 n);

       mlib_status mlib_MatrixUnit_S8C(mlib_s8 *z, mlib_s32 n);

       mlib_status mlib_MatrixUnit_S16(mlib_s16 *z, mlib_s32 n);

       mlib_status mlib_MatrixUnit_S16C(mlib_s16 *z, mlib_s32 n);

       mlib_status mlib_MatrixUnit_S32(mlib_s32 *z, mlib_s32 n);

       mlib_status mlib_MatrixUnit_S32C(mlib_s32 *z, mlib_s32 n);

DESCRIPTION
       Each of these functions sets the values for a unit matrix.

       For real data, the following equation is used:

       z[i*n + j] = 1  if i == j
       z[i*n + j] = 0  if i != j

       where i = 0, 1, ..., (n - 1); j = 0, 1, ..., (n - 1).

       For complex data, the following equation is used:

       z[2*(i*n + j)]	  = 1  if i == j
       z[2*(i*n + j)]	  = 0  if i != j

       z[2*(i*n + j) + 1] = 0

       where i = 0, 1, ..., (n - 1); j = 0, 1, ..., (n - 1).

PARAMETERS
       Each of the functions takes the following arguments:

       z	       Pointer to the destination matrix.

       n	       Number of rows and columns in the matrix.

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