Hello! I have a vector that I need to integrate over the sections, the length of the section is 3
% now I use such a loop, but it gives me 900 answers, but should 300
for i=1:length(Fi)
x=Fi(i:i+2); % +2 I need to integrate sections (3 values ​​per section)
LayerDepstep(i)=trapz(x);
end
% x=900 % 300
% Fi vector 1:900 %

Perhaps you should have something like:
for i=1:4:length(Fi)-2
x=Fi(i:i+2); % +2 I need to integrate sections (3 values ​​per section)
LayerDepstep(floor(i/4)+1)=trapz(x);
end

i tested this method but it didn't help me

It does what you appeared to be asking for, i.e. reduces the number of sections by a factor of 3. What problem remains?
