Ran in:
% example data
Sis.PV = 20;
% Sis.PV = repmat(Sis.PV,1,82); % original incorrect line, expanded the field instead of the struct
Sis = repmat(Sis,1,82); % correct line, expands the struct
Sis
Sis = 1×82 struct array with fields:
PV
sum([Sis.PV])
ans = 1640
See this tutorial on how to use comma separated lists.

Yes, I used []. Read the tutorial at the link I provided in the answer for more info. And/or search the doc for "comma-separated lists".

I just realized I had a mistake in my example. I'll edit the Answer.
