Thread Subject: Parallel M-File S-Function

Hi,
I would like to know if a Level 2 M-File S-Function can include parfor loops in its code or, as is my understanding, in Simulink you can only run parallel simulations of the same model.

Many thanks in advance,

francesco

I don't know of any specific restrictions here, and got things working with an
outputs function like this:

%%%
function Outputs(block)
    total = 0;
    parfor ii=1:floor(block.InputPort(1).Data)
        total = total + ii;
    end
    block.OutputPort(1).Data = total;
end
%%%

(Of course, this is a very inefficient PARFOR loop!)

Cheers,

Edric.
