NAME

mlib_VectorAng_U8C, mlib_VectorAng_S8C, mlib_VectorAng_S16C, mlib_VectorAng_S32C - vector complex phase (angle)  

SYNOPSIS

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

mlib_status mlib_VectorAng_U8C(mlib_d64 *a, 
    const mlib_u8 *x, mlib_s32 n);

mlib_status mlib_VectorAng_S8C(mlib_d64 *a, 
    const mlib_s8 *x, mlib_s32 n);

mlib_status mlib_VectorAng_S16C(mlib_d64 *a, 
    const mlib_s16 *x, mlib_s32 n);

mlib_status mlib_VectorAng_S32C(mlib_d64 *a, 
    const mlib_s32 *x, mlib_s32 n);

 

DESCRIPTION

Each of these functions computes the phase vector of a complex vector.

The following equation is used:

a[i] = atan(x[2*i + 1] / x[2*i])

where i = 0, 1, ..., (n - 1).  

PARAMETERS

Each of the functions takes the following arguments:

a

Pointer to the destination phase vector.

x

Pointer to the source vector

n

Number of elements in the vector.

 

RETURN VALUES

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