NAME

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

       mlib_status mlib_VectorConjSymExt_S8C_S8C_Sat(mlib_s8 *z,
	    const mlib_s8 *x, mlib_s32 n);

       mlib_status mlib_VectorConjSymExt_S16C_S16C_Sat(mlib_s16 *z,
	    const mlib_s16 *x, mlib_s32 n);

       mlib_status mlib_VectorConjSymExt_S32C_S32C_Sat(mlib_s32 *z,
	    const mlib_s32 *x, mlib_s32 n);

DESCRIPTION
       Each of these functions computes the complex conjugate extension of a complex vector.

       The source and destination vectors must be in the same data type.

       When n is even, the following equation is used:

	 z[2*i]     =  x[2*i]
	 z[2*i + 1] = -x[2*i + 1]

       for i = 0, 1, ..., (n - 1).

	 z[2*i]     =  x[2*(2*n - 1 - i)]
	 z[2*i + 1] = -x[2*(2*n - 1 - i) + 1]

       for i = n, (n + 1), ..., (2*n - 1).

       When n is odd, the following equation is used:

	 z[2*i]     =  x[2*i]
	 z[2*i + 1] = -x[2*i + 1]

       for i = 0, 1, ..., (n - 1).

	 z[2*i]     =  x[2*(2*n - 2 - i)]
	 z[2*i + 1] = -x[2*(2*n - 2 - i) + 1]

       for i = n, (n + 1), ..., (2*n - 2).

PARAMETERS
       Each of the functions takes the following arguments:

       z    Pointer to the first element of the destination vector.

       x    Pointer to the first element of the source vector.

       n    Number of elements in the source vector.

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