How do I solve this ODE system containing symbolic matrices ?

Initial Conditions: k1(0)=0; k2(0) = 0

All the variables in the equations are matrices. M,A,F,C etc are known. I(t) has been evaluated and is to be substituted in the second equation. It's of the form I(t)=k2(0)+k2(1)+k2(3)+....k2(t)

I had defined k2 as symbolic matrix of (t,1) size. Should I also define k1 of a similar size symbolically and proceed?

I am sorry but this is my first Matlab attempt. I am attempting to use it to countercheck my experimental results. i am not familiar with which ode solver to use.

I am very grateful for your help in advance.
