I have this:
for t=0;1.:30
CODE OF Model
end
The result of the code is C (matrix 1000x1000).
I would like "Ctotal" to be the sum of C(t=1)+C(t=2).....C(t=30).
Thanks.
PS: I'm Italian what is "doc sum"?

sum(C(1:30))
If you evaluate at the MATLAB command line:
>>doc sum
It will tell you all about summing.

eg
res=0
for k=1:5
M=rand(4);
res=bsxfun(@plus,res,M)
end
