Hello, Given a system of differential equations as: C*V = O; where O is a null matrix and C is a 3X3 matrix as follows: Row 1: [rho*(alpha*I+omega*U*I), rho*U', alpha*I] Row 2: [0, rho*(alpha*I+omega*U*I), d/dy] Row 3: [alpha*I, d/dy, M^2*(alpha*I+omega*U*I)] The prime in Row 1 denotes differentiation with respect to y, and I is the unit imaginary number, d/dy is a differential operator. The vector V is given by: V = [u; v; w]; How do I use Maple to do a Gauss Elimination on the coefficient matrix which will give me separate equations for each of u, v and w. Or to be more specific, how do I represent the differential operator d/dy in a matrix
