doc sum

?

[Edoardo]

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"?

[Sean de Wolski]

sum(C(1:30))

If you evaluate at the MATLAB command line:

>>doc sum

It will tell you all about summing.

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