Hi!,

I've got error message when I generate the hdl code in MATLAB the below code,

    Incorrect number of output arguments for 'pre_test_fixpt'. Expected 1, but found 2.

But I can't get it, What does "Incorrect number of output arguments for 'pre_test_fixpt'. Expected 1, but found 2." mean? How can I resolve this problem?

this is test code

     srcX = 4;
                 srcY = 4;
                 dstX = 32;
                 dstY = 32;
                 rep_dstXminus_one = 1/(dstX-1);
                 rep_dstYminus_one = 1/(dstY-1);
                 a00 = pre_test(srcX,srcY,dstX,dstY,rep_dstXminus_one,rep_dstYminus_one);

This is function code

    function a00 = pre_test(srcX,srcY,dstX,dstY,rep_dstXminus_one,rep_dstYminus_one)
       for y = 1:255
           for x = 1:255
                a00 = y*x + srcX + srcY + dstX +dstY + rep_dstXminus_one +rep_dstYminus_one;
           end
       end
    end
