When trying to find the fundamental solution of the Heat equation using Maple (software), I get the following Error message which seems to have no documentation available (?) :
PDE := -(diff(f(x, t), t))+(diff(f(x, t), x, x))*Di = 0
assume(epsilon > 0);
pdsys := [PDE, f(x, 0) = Dirac(x-epsilon)];
"Error, (in casesplit/K) this version of casesplit is not yet handling the function: Dirac"
Anybody has an idea what that is? (Using Maple 17) . How can I solve this problem ?
Thanking you on Advance,
