NAME
     mlib_VectorMag_U8C, mlib_VectorMag_S8C, mlib_VectorMag_S16C,
     mlib_VectorMag_S32C - vector complex magnitude

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_VectorMag_U8C(mlib_d64 *m, const mlib_u8 *x,
          mlib_s32 n);


     mlib_status mlib_VectorMag_S8C(mlib_d64 *m, const mlib_s8 *x,
          mlib_s32 n);


     mlib_status mlib_VectorMag_S16C(mlib_d64 *m, const mlib_s16 *x,
          mlib_s32 n);


     mlib_status mlib_VectorMag_S32C(mlib_d64 *m, const mlib_s32 *x,
          mlib_s32 n);


DESCRIPTION
     Each of these functions computes the magnitude vector of the
     complex input vector.


     The following equation is used:

       m[i] = (x[2*i]**2 + x[2*i + 1]**2)**0.5



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

PARAMETERS
     Each of the functions takes the following arguments:

     m    Pointer to the destination magnitude 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.
