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

     mlibstatus mlibMatrixTransposeU8(mlibu8 *xz, mlibs32 mn);


     mlibstatus mlibMatrixTransposeU8C(mlibu8 *xz, mlibs32 mn);


     mlibstatus mlibMatrixTransposeS8(mlibs8 *xz, mlibs32 mn);


     mlibstatus mlibMatrixTransposeS8C(mlibs8 *xz, mlibs32 mn);


     mlibstatus mlibMatrixTransposeS16(mlibs16 *xz, mlibs32 mn);


     mlibstatus mlibMatrixTransposeS16C(mlibs16 *xz, mlibs32 mn);


     mlibstatus mlibMatrixTransposeS32(mlibs32 *xz, mlibs32 mn);


     mlibstatus mlibMatrixTransposeS32C(mlibs32 *xz, mlibs32 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  MLIBSUCES  if  successful.
     Otherwise it returns MLIBFAILURE.
