However, I failed and got an TypeError (This returns the following error: TypeError: Computation failed since Maxima requested additional constraints; using the 'assume' command before evaluation may help).
Here is my code for it. Could anyone help me with this? Thank you.
A=Matrix([[5/3, -4/3], [4/3, -5/3]])
B=Matrix([[2],[1]])
C=Matrix([-1,2])
D=Matrix([0])
t = var('t')
X=symb_mat(2,1,'X',t);
diffeqns = [eql == eqr \
for (eql,eqr) in zip(*[diff(X,t).list(),(A*X+B*u).list()])]
desolve_system(diffeqns,X.list(),ics=[0,1,2],ivar=t)jncn5565Fri, 08 Mar 2019 18:47:49 -0600http://ask.sagemath.org/question/45730/
