Calculates the matrix vector product of a distrubted matrix times a distributed vector and adds it to the distributed product vector. NOTE: This will only work for specific CMISS distributed matrices i.e., ones in which the columns of the matrix are distributed in the same way as the rows of the multiplied vector are distributed, and the rows of the matrix are distributed in the same way as the rows of the product vector.

Parameters
