I want to use the Kroneckerdelta function in my programming.I also check the syntax for it. It is given as kroneckerDelta(m,n).But when i used this syntax in my programming it is showing error Undefined function 'DiracDelta' for input arguments of type 'double'.What does it mean?

What version of MATLAB you are using? Does help Kroneckerdelta gives details about the function?

You are doing this:
kroneckerDelta(2,3)
Undefined function 'kroneckerDelta' for input arguments of type 'double'.
As you see, MATLAB fails to work, even though I have the symbolic TB, in the current release. Why does it fail? Because I called it with double precision arguments. That function is part of the symbolic TB. In order for it to work, the arguments (at least one of them) must be symbolic.
kroneckerDelta(sym(2),3)
