Hello everyone.... I want to solve a sytem of ordinary differential equation....the coefficent of this system are Matrices....I try to find in help but I don't find any result.... the system is in this form A'[t] = D[t]*A[t]+2*C with a initial condition A[0] = {0,0} and t's gap {t,0,300} I try to write this with NDSolve but it return me a error NDSolve[{A'[t] = D[t]*A[t]+2*C,A[0] = {0,0}},A,{t,0,300}] Naturally D[t] is a matrix 2x2 and C is a columm of 2 element the dimension of matric D and C are ok but i don't know if i should declare A[t] as a variable matrices.... the error that return NDSolve is NDSolve::deql : The First argument must have both an equation and an initial condition. thanx for help -- AMS Michelin@ingegneriaPOINTunimePOINTit
