In the above table, the notation (A-t) means that this matrix need not be passed, but the user may choose to pass an explicit transpose of matrix A (for improved efficiency).
Also note that some of the equation types impose restrictions on the properties of the coefficient matrices and possibly on the right-hand side C.
