mediaLib Library Functions  mlib_MatrixMulSShift_U8_U8_Mod(3MLIB)



     Each of these  functions  performs  a  multiplication  of  a
     matrix with a scalar and shifts the result.


     For real data, the following equation is used:

       z[i] = c[0]*x[i]*2**(-shift)



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


     For complex data, the following equation is used:

       z[2*i]     = (c[0]*x[2*i] - c[1]*x[2*i + 1])*2**(-shift)
       z[2*i + 1] = (c[1]*x[2*i] + c[0]*x[2*i + 1])*2**(-shift)



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


     The ranges of valid shift are:

       1 < shift < 8   for U8, S8, U8C, S8C types
       1 < shift < 16  for S16, S16C types
       1 < shift < 31  for S32, S32C types


PARAMETERS
     Each of the functions takes the following arguments:

     z        Pointer to the destination matrix.


     x        Pointer to the source matrix.


     c        Pointer to the source scalar. When the function  is
              used  with  complex  data  types, c[0] contains the
              scalar for the real part,  and  c[1]  contains  the
              scalar for the imaginary part.


     m        Number of rows in each matrix.


     n        Number of columns in each matrix.

     shift    Right shifting factor.


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