plz how to solve a Nonlinear differential equation greetings Is that someone can help me solve a nonlinear difirential equation in matlab like
M(t)*q'''(t)+ C(t)*q''(t) +K(t)*q(t)=F(t)
M, C, and K are matrices, and F is a vector
Plzzzzzzzzzzzzz

Is this an initial value problem? I.e., can you use e.g. ode45 for this? As written above, this looks like a linear differential equation to me (linear in q and its derivatives). Is M(t) always invertible? Can you give us more details about the size of q and the form of M, C, K, and F?
