Plotting inverse laplace w.r.t.

How can I plot inverse laplace of a fucntion which contains exponential and hyperbolic functions on Matlab? like

(0.2696)/(s-0.1384*(s^1)*((exp(1.2468*s)+exp(-1.2468*s))/((exp(1.2468*s)-exp(-1.2468*s)))))

Hi Yash

You can use ilaplace function to compute the inverse laplace of H as shown below.

h=matlabFunction(ilaplace(H));
t=1:0.01:100;
plot(t,h(t))

Hi Vishnu,

ilaplace wroks only for simple functions. In this case it throws back to me the orginal function.

From the documentation page it looks like the inputs can be symbolic expression | symbolic function | symbolic vector | symbolic matrix and also given that if it cannot compute the inverse then it returns an unevaluated call to ilaplace.Hence you are observing that results.
