MATLAB: Manage time computing

Question

Hi,

I would like to manage the computing time of a function. For example :

function y = myfun(x)
y = something_long_to_calculate(x);
return

and I would like my main code to do something like:

lim = 5; %time limit in sec
x = 0;
tic;
while toc<lim
y = myfun(x);
end

Obviously, I wouldn't work, the point is how could you limited the time of calculation. In this case, if y should have been a vector 100×1 and the program would just have had time to compute the 10 first iterations, how could I still got those values ?

thx

That looks like it would work. For a different coding, see http://www.mathworks.com/matlabcentral/answers/21721-constructing-for-loop-in-terms-of-seconds
