MATLAB: Simpl equestion about CUMSUM

cumsumfor loopMATLABoptimizationsum

How can I rewrite the following code using cumsum?
    for i=0:299
        A(i+1)=sum(B > i);
    end
Many thanks!

I don't think I would use cumsum here. Instead, try
A = sum(bsxfun(@gt,B',0:299));
Note, this command above assumes B is a row vector (the 1-by-35535 vector you mention).
