Starting from this information, I have managed to obtain this state representation. I wanted to ask for your confirmation to know if it is correct, or if it is not, where I made a mistake. Thank you for your attention.
this are my matrix :
A = [ 0 1 0 0 0 0;
-k0/m1 0 k0/m1 0 0 0;
0 0 0 1 0 0;
0 0 -k0/m2 0 k0/m2 0;
0 0 0 0 0 1;
0 0 0 0 -k0/m3 0];
B = [1/m1;
0;
0;
0;
0;
0];
C = [1 0 0 0 0 0];
D = 0;

The k terms in the equations above appear to be non-linear. Your A matrix doesn't account for the cubic parts.
