Directly accessing matrix values within a for-loop

Question

If I have a matrix containing:

How can I use the numbers held within 'n' to specify the number of iterations a for-loop should contain? i.e. I want the loop to do 49898 iterations before moving on to do 148954 and so forth. I have other nested for-loops which also need to advance by '1' once 49889 or 148954 etc. complete thus I can not just SUM 'n'. I know only of:

for i=n and for i=1:n styles of for-loop, neither of which solves this issue.

Use a nested for-loop:

for i=1:length(n)
    for j=1:n(i)
        % do something
    end
end

It is best [not to use `i` and `j` as variable names in Matlab](http://stackoverflow.com/questions/14790740/using-i-and-j-as-variables-in-matlab) – Shai Sep 18 '14 at 06:31
