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.h>

       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.
