As a hack for this release could you have the Numeric portion of the multiply routines check if the symbolic data is there and if not just call the symbolic an attach the needed data? You might need to have a utility function that does all the symbolic
part except the allocation of the matrix and then call this from the numeric part as well as the real symbolic part.<br>
