NAME
     mlib_MatrixTranspose_U8,           mlib_MatrixTranspose_U8C,
     mlib_MatrixTranspose_S8,           mlib_MatrixTranspose_S8C,
     mlib_MatrixTranspose_S16,         mlib_MatrixTranspose_S16C,
     mlib_MatrixTranspose_S32, mlib_MatrixTranspose_S32C - matrix
     transpose, in place

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

     mlib_status mlib_MatrixTranspose_U8(mlib_u8 *xz, mlib_s32 mn);


     mlib_status mlib_MatrixTranspose_U8C(mlib_u8 *xz, mlib_s32 mn);


     mlib_status mlib_MatrixTranspose_S8(mlib_s8 *xz, mlib_s32 mn);


     mlib_status mlib_MatrixTranspose_S8C(mlib_s8 *xz, mlib_s32 mn);


     mlib_status mlib_MatrixTranspose_S16(mlib_s16 *xz, mlib_s32 mn);


     mlib_status mlib_MatrixTranspose_S16C(mlib_s16 *xz, mlib_s32 mn);


     mlib_status mlib_MatrixTranspose_S32(mlib_s32 *xz, mlib_s32 mn);


     mlib_status mlib_MatrixTranspose_S32C(mlib_s32 *xz, mlib_s32 mn);


DESCRIPTION
     Each of these functions performs an in-place transpose of  a
     square matrix.


     For real data, the following pseudo code applies:

       for (i = 1; i < mn; i++) {
           for (j = 0; j < i; i++) {
               tmp          = xz[i*mn + j];
               xz[i*mn + j] = xz[j*mn + i];
               xz[j*mn + i] = tmp;
           }
       }

     For complex data, the following pseudo code applies:

       for (i = 1; i < mn; i++) {
           for (j = 0; j < i; i++) {
               tmp0                 = xz[2*(i*mn + j)];
               tmp1                 = xz[2*(i*mn + j) + 1];
               xz[2*(i*mn + j)]     = xz[2*(j*mn + i)];
               xz[2*(i*mn + j) + 1] = xz[2*(j*mn + i) + 1];
               xz[2*(j*mn + i)]     = tmp0;
               xz[2*(j*mn + i) + 1] = tmp1;
           }
       }


PARAMETERS
     Each of the functions takes the following arguments:

     xz    Pointer to the source and destination matrix.


     mn    Number of rows and columns in the matrix.


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