DESCRIPTION

Each of these functions multiplies a vector by a matrix.

For real data, the following equation is used:

       m-1
z[i] = SUM (x[j] * y[j*m + i])
      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)
            j=0

            m-1
z[2*i + 1] = SUM (xR*yI + xI*yR)
            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 elements in the source vector.

n

Number of columns in the matrix, and number of elements in the destination vector.

 

RETURN VALUES

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