Hi,

how can I plot result of inverse Laplace transformation?

Example:

```b=(s^2-2*s+4);
c=ilaplace(b)
t=0:10;
```

Than I get:

```c = 4*dirac(t) - 2*dirac(t, 1) + dirac(t, 2)
```

but how can I plot result of ilaplace for t=0:10?

```ezplot(matlabFunction(h), [1,1000])
```

but it doesn't work.

Thank you for help

No ideas?

Hey..

When you say you want to plot the inverse laplace transform don't you actually mean the impulse response of the system? Because then you might as well plot the impulse response using impulseplot function. But then you also need to define the system. Just asking because I am working on a similar topic.

Hi, I want just plot my above example for any time interval...I hope it is answer for your question. :-). But I dont know how.

Inverse laplace transform plot of a transfer function, F, is equal to impulse response of the transfer function, F. You could simply do, impulseplot(F). Note that F is 'tf' type and 'sym' type.
