Open in MATLAB Online Since the "fplot" function accepts a symbol expression, you can simply add more symbolic data to it before calling the function. Here is a trivial example of this technique: ThemeCopy syms x y = x; g = (x-2); fplot(y+g) Notice how I added two symbolic fun...
A quick test of the code is in order. First, does it do what we expected in terms of symbolic manipulations? a = sym('a',[1,5]) a = [ a1, a2, a3, a4, a5] symsx y = myhorner(a,x) y = a1 + x*(a2 + x*(a3 + x*(a4 + a5*x))) ...

title('phiddot vs time, symbolic computation') This suggests that your formula for phiddot is incorrect. You have exp(t) kind of function, and the derivative of that is not going to be t^2 - t kind of function. Sign in to answer this question. ...
