Hi all,

I've a function that returns multiple results in a structure (i.e results.m1, results.m2). As running this function each time is computationally intensive with many simulations within it, I am attempting to put this in a parallel computing environment, as follows:

    parfor z = 1:8
          results=function(x,y,z);
    end

My question then is: How can I get the function to return me 8 different structures containing my results? I can't seem to get it to do so.

Would love to have some help here.

Thanks :)

Why not create a struct array as follows?

    parfor z = 1:8
          results(z)=function(x,y,z);
    end

I actually tried that. It gives me an error telling me "The expression to the left of the equals sign is not a valid target for assignment". Any idea why this might be the case?

Whatever it is, it's not coming from code you've shown us. Try running the simplified example below as an mfile. You should find that it works fine.

    function test
        parfor z = 1:8
              results(z)=makestruct(z);
        end
    results
    function S=makestruct(z)
     S.a=z;
     S.b=z;
