Are you sure you have the Symbolic Math Toolbox installed? It looks like you don't.
Please run the ver command and look if the Symbolic Math Toolbox is listed. If not, than you haven't installed it. That would be the reason why you get the error above.
I hope I could help

Hi,
try to run the which command to see if the function is available:
>> which -all heaviside
The output should look like this:
C:\Program Files\MATLAB\R2010b\toolbox\symbolic\symbolic\heaviside.m
If you can't locate the function try a
>> restoredefaultpath
and try again to call this function
