Why do I receive an error message about output arguments for my Embedded MATLAB Function in Simulink?

I have if-else statements in my code to output different results in different situations. When I start the simulation I get the following error message.. I hope you can help me. Thank you
Output argument 'D' is not assigned on some execution paths.
Function 'MPPT /IC Algo' (#182.9.10), line 1, column 10: "D"
function D = InCon(V,I,T)

The error message suggests that your D is not assigned for certain input combination. without the code itself, it would be hard for people to provide useful suggestions.
ok, I am attaching the coding file. Thank you

Simulink wants to know the initial value and size of your output at the very beginning of the simulation. Therefore, add
D=0;
statement to your function at the very beginning. Then, it should work without error.

Then check your if-else statements and make sure that they are being entered because your value should have changed.
I can't get your answer

Your D is undefined for the cases where T<=n*0.005
You can consider add that by adding the else branch to the code, for example,
if T>n*0.005
... % what you have now
else
D = Dold;
end
