I have a system of 4 first-order differential equations which can be solved with odesolve.
I want to use the statespace function, but it fails with a cryptic message. My system matrix is not in canonical form, but the documentation for statespace does not seem to require it. I am probably making some stupid mistake, but I don't see it.
Attached are Prime 6 worksheet and pdf.
Solved! Go to Solution.
Went back to Mathcad 15 and errror message said "A"must be a function.
Went back to Prime documentation, and lookie lookie: "A is an n x n matrix function of the form A(t), where n is the number of unknown states. The entries of A(t) are functions of the independent variable t.".
