Hi everyone

Can you help me for my code about GPU?

I want to use gpu to mutiply 2 matrix different size.

to speed up, I use arrayfun. it gets error.

so i dont know how to mutiply 2 matrix.

this is my code.

    function c = myCal(rawdata, gain)
    c = (rawdata .* gain);
    end
   meas = gpuArray(ones(1,10)*3);
   gn   = [1 2 3 4 5 6 7 8 9 10;
          2 3 4 5 6 7 8 9 2 1]';
   gn = gpuArray(gn);
   corrected = arrayfun(@myCal,meas,gn);
   results = gather(corrected);
