Hi,
I need to do the following double summation ∑(i=0,2)∑(j=0,3)〖(2i+3j)〗in a MATLAB program. The answer should be 78. Thank you.

Please just accept the answer you are happy with. Don't add your own answer to just say which answer works and then accept that! You can add comments to people's answers.

There are likely several ways to code this (I assume this is a coding exercise, since the correct answer is provided).
This is one approach:
i = 0:2;
j = 0:3;
[I,J] = meshgrid(i, j);
f = @(i,j) 2*i + 3*j; % Anonymous Function
fmtx = f(I,J);
Answer = sum(fmtx(:))
I am not documenting it, leaving it for you to understand how it works.
