Hi, I'm using R2006b and I'm trying to use the ilaplace
function, but matlab seems to have no idea what it is. When
I type in 'syms s' or ilaplace(anything) it gives me:
Undefined function or method 'ilaplace' for input arguments...

I've used ilaplace before on campus computers with a certain
versions, but now I can't get it to work on any computer.

Hello Bryan,

Symbolic Math Toolbox is required.

What is ANYTHING? is anything a function of the symbol 's' ?

ilaplace is part of basic symbolic toolbox, which I understand is part
standard matlab, so you should have it.

Try this example to see if it works with you. I think you have given
ilaplace the wrong argument type that is why you got the error.

EDU>> syms s;
EDU>> f=1/s;
EDU>> ilaplace(f)

ans =

Minimum system requirements:

1. Valid credit card (not maxed-out)
2. Working telephone
3. 'Normal' IQ

Go ogle this: http://www.mathworks.com/support/cs/index.html

Alternate:

Find the IT support person at CSM; querey - license update(s).

So if the symbolic toolbox is part of normal matlab, why
doesn't this toolbox work? Everything else in matlab works.
Some computers on campus have R2006b and some have matlab14.
Neither syms, nor ilaplace() work on either version. I'm
pretty sure it's not expired.

Use the command 'ver' to see if you have the toolboxes needed.

Check for the symbolic toolbox (basic version), it should be listed. If it
is not listed, then it is possible that something went wrong with
installation, or may be there are Matlab installations which do not come
with basic symbolic toolbox (even though I did not think so). Check with
you school lab IT guru who does the software support and let them know.
