for loops.
显示 更早的评论
Hello! Please, how can I implement an iteration, such that a first loop executes a series of expressions within a range of (32) values and a second loop executes a series of expressions within another range of(16) values for each result of the first iteration. the result of this would be 512 iterations. Thank u.

Are the values independent or does the first loop need to complete before the second loop could start?

I guess you mean nested loops?
for ni=1:32
for nj=1:16
% Do something here?
end
end

Or maybe
parfor ni=1:32
for nj=1:16
%do something here?
end
end
But that presumes that each if the nj loops does not need results from a different ni loop, a point I explicitly questioned.
Depending what exactly has to be done, this might even be a case for co-distribution using for ni = drange(1:32)

parfor ni=1:32
%do first thing here
end
parfor ni=1:32
for nj=1:16
%do second thing here
end
end
It would, though, not surprise me if the first parfor would be more efficient as a for loop -- depends how much work is done in the first part.
