Only the symbolic toolbox has a delta function, where it is called dirac()
http://www.mathworks.com/help/toolbox/symbolic/dirac.html

It is, however, not a correct mathematical Dirac Delta:

http://en.wikipedia.org/wiki/Dirac_delta_function

"From a purely mathematical viewpoint, the Dirac delta is not strictly a
function, because any real function that is equal to zero everywhere but
a single point must have total integral zero."
