ploting reversed laplace function

Why is it not working?, please help syms s; y =(4.36/(s*(s^2+1.61*s+0.935+4.36))); ilaplace(y) t = 0:0.001:8; plot(t,y, '-r' )

[eliman]

syms s;

y =(4.36/(s*(s^2+1.61*s+0.935+4.36)));

ilaplace(y)

t = 0:0.001:8;

plot(t,y, '-r' )

Thanks for formatting the code. It would be better, though, to edit your original question.

In your question you should also say how it is not working. In this case, you are getting an error message:

??? Error using ==> plot

Conversion to double from sym is not possible.

The Symbolic Toolbox does not substitute numeric values of t into the expression unless you ask it to. You could do this:

plot(t,subs(y,t),'-r')
