I am using the ilaplace command and I receive the command and argument as my result instead of the transform.

Here's my script:

syms t s
ilaplace(1/(s-1))

and here's the output

ans =
ilaplace(1/(s-1),s,t)

Any thoughts?

Thanks,
MB

Here is my output from the latest MATLAB version, and also from R2008b:

>> syms s t
>> u = ilaplace(1/(s-1))

u =

exp(t)

It seems to me that there is something wrong with your Symbolic
Toolbox(TM) installation. Are you using a very old version of the
toolbox? In any case, you might want to call technical support and/or
reinstall.
