Yes, in MATLAB you can absolutely use two symsum functions together, one for each symbolic variable, to represent double summation.
Below is a basic implementation of how to do it with two symbolic summations:
syms i j
% Define the expression to sum over
expr = i + j; % Example: any symbolic expression involving i and j
% Double summation: outer sum over i = 0 to 786, inner sum over j = 0 to 1024
total_sum = symsum(symsum(expr, j, 0, 1024), i, 0, 786);
For better understanding of "symsum" refer to the following documentation:
Hope this helps!
