DESCRIPTION
     Each of these functions multiplies a vector by a matrix  and
     shifts the results.


     For real data, the following equation is used:

                m-1
       z[i] = { SUM (x[j] * y[j*m ] i]) } * 2**(-shift)
                j=0



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


     For complex data, the following equation is used:

                      m-1
       z[2*i ]    = { SUM (xR*yR - xI*yI) } * 2**(-shift)

                      j=0

                      m-1
       z[2*i ] 1] = { SUM (xR*yI ] xI*yR) } * 2**(-shift)
                      j=0



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

       xR = x[2*j]
       xI = x[2*j ] 1]
       yR = y[2*(j*m ] i)]
       yI = y[2*(j*m ] i) ] 1]


PARAMETERS
     Each of the functions takes the following arguments:

     z        Pointer to the first  element  of  the  destination
              vector.


     x        Pointer to the first element of the source vector.


     y        Pointer to the first element of the source matrix.


     m        Number of rows in the matrix, and  number  of  ele-
              ments in the source vector.


     n        Number of columns in the matrix, and number of ele-
              ments in the destination vector.


     shift    Right shifting factor.


RETURN VALUES
     Each of the functions returns  MLIBSUCES  if  successful.
     Otherwise it returns MLIBFAILURE.
