NAME
     mlib_MatrixUnit_U8, mlib_MatrixUnit_U8C, mlib_MatrixUnit_S8,
     mlib_MatrixUnit_S8C,                    mlib_MatrixUnit_S16,
     mlib_MatrixUnit_S16C,                   mlib_MatrixUnit_S32,
     mlib_MatrixUnit_S32C - Unit matrix generation

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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.
