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_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  com-
     plex 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.
