For a series RLC circuit, If L = 10 H, R = 400 Ohms and C = 100µF, i(0) = 4 A and di/dt(0) = 15 A/s.
The 2nd ODE solution for i(t) is:
$\frac{d^2i(t)}{dt^2} + \frac{400}{10}\frac{di(t)}{dt} + 1000i(t)$
Script
1 syms y(t)
2 Di = diff(y);
3 ode = diff(y,t,2) + 1000*y == 0;
4 cond1 = y(0) == 4;
5 cond2 = Di(0) == 15;
6 conds = [cond1 cond2];
7 y(t) = dsolve(ode,conds);
8 y2 = matlabFunction(y);
9 fplot(y2)
Assessment:
Are you using matlabFunction for y?
