KroneckerDelta in matlab

This link shows that there is a kronecker delta function in matlab. However:

>> help kroneckerDelta

    kroneckerDelta not found

I am using R2011b, so maybe this wasn't programmed into the toolkit yet?

EDIT:: It works in MuPad, just not in matlab...

.

Solution

  • I don't see it in my R2012b so perhaps not. Unless you need the symbolic math, you could always write your own. Something as simple as

    function d = kronDel(j,k)

if j == k
    d = 1;
else
    d = 0;
end
