system of differential equations solving

Hello all

I have a system of differential equations which can be expressed as dE(z)/dz=S(z)E(z), where S(z) is 6x6

Any way to solve it using MATLAB or another way? I know how to write the eigenvalues and eigenvectors as functions of z using syms z, but I do not know how to continue?

Any help please

And ‘E(z)’ is ... ?
