I am using the ilaplace command from matlab and it keeps spitting out the dirac delta function. I typed the exact command in the matlab help section and it still gives me this. for example I type in this...

ilaplace(1/(s-1))

and I get this...

1 - dirac(t)

below is a copy of matlab help file that has this exact command with the result I'm after.

Examples:
syms s t w x y
ilaplace(1/(s-1)) returns exp(t)

Any help would be great. I'm thinking it is some format command or something beforehand.
