I have to use "emd" function for 500 signals and 100 times for each of them. As a result I developed a code like below:

for ii = 1 : 500
    for jj = 1 : 100
        [output1, ouput2, output3] = emd(awgn(signal(:,ii),20));
    end
end

But performance of code is very low and my laptop is going to explode.

Is there any trick to improve the code?
