NAME

mlib_VectorSplit_U8_U8C, mlib_VectorSplit_S8_S8C, mlib_VectorSplit_S16_S16C, mlib_VectorSplit_S32_S32C - vector split  

SYNOPSIS

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

mlib_status mlib_VectorSplit_U8_U8C(mlib_u8 *r, mlib_u8 *i, 
    const mlib_u8 *x, mlib_s32 n);

mlib_status mlib_VectorSplit_S8_S8C(mlib_s8 *r, mlib_s8 *i, 
    const mlib_s8 *x, mlib_s32 n);

mlib_status mlib_VectorSplit_S16_S16C(mlib_s16 *r, mlib_s16 *i, 
    const mlib_s16 *x, mlib_s32 n);

mlib_status mlib_VectorSplit_S32_S32C(mlib_s32 *r, mlib_s32 *i, 
    const mlib_s32 *x, mlib_s32 n);

 

DESCRIPTION

Each of these functions splits a complex vector into separate vectors containing the real and imaginary parts.

The following equation is used:

r[k] = z[2*k]
i[k] = z[2*k + 1]

where k = 0, 1, ..., (n - 1).  

PARAMETERS

Each of the functions takes the following arguments:

r

Pointer to the first element of the real part.

i

Pointer to the first element of the imaginary part.

x

Pointer to the first complex element of the source vector. x[2*k] contains the real part, and x[2*k + 1] contains the imaginary part.

n

Number of elements in the vectors.

 

RETURN VALUES

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