Question: Initial Value Problem

I have an initial value problem B(Y,t)(dY/dt)=C(Y,t), where Y= sought vector function, B matrix of the vector function and the independant varaible t, C is a column of function of Y and t.

In my case, B is a 21x21 matrix, but if I can increase the size of the matrix, it could be better.

I tried to solve the problem by creating a system of diffferential equations and using the dsvolve command. It didn't work.

How to efficiently solve this problem?
