I try to write the below formula:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/154968/image.png)
h=sum(H1(l*m)^r);
Is that true in your opinion?
Thanks for the help.

It depends on the context, but your code is probably wrong. You have some variable H that seems to vary according to i, l and j. If you have set up your H such that l varies along a column, you can write
h = sum(H)
where j and l could are varying along the 2nd and 3rd dimension.

Yes. sum sums over the first dimension, which is l in your case. And that's what the formula says.
BTW:
S = sum(X,DIM) sums along the dimension DIM.
