What is syntax of Kronecker Delta in MATLAB Version R2013a

As per suggestion i wrote the following code but still it is showing the error "double type error". for i=1:1:n+5 C1(1,1)=0.030792+0.009208; C1(i,1)=(0.009208*((-0.00000588235)^(i-1))/factorial(i-1));

    end

for j=1:1:n+1 for i=1:1:n+1 C1(i,j+1)=(a*i*C1(i+1,j)-b*C1(i,j)+c*(C2(i,j)-C1(i,j))+D1*i*(i+1)*C1(i+2,j))+kroneckerDelta(i-0,j-0)/j;

end
end

From the documentation:

"For kroneckerDelta with numeric inputs, use the eq function instead."

sir your are asking me to call a function

[Torsten]

Use

double(eq(i,j))

instead of

kroneckerDelta(i,j)

By the way: KroneckerDelta is also a function ...

Hi what does "double" do here

[Torsten]

Convert logical to double ?

Maybe since eq(i,j) is 0 or 1, conversion is not needed.
