You'd better give one example (one formula) which you want to create.

Is dx1 intended to represent the derivative of x1? If so then is part of the task to figure out what the function is? Something like
syms x1(t) x2(t) u
eqn = [diff(x1(t),t) == -x1(t) + x1(t)*x2(t) + u; diff(x2(t)) == 2*x1(t)-3*x2(t), x1(0) == 1, x2(0) == 0]
dsolve(eqn)
??

The above system has no general solution and runs into a singularity at about t = 1.33
