I also think that the conjugate should be taken. I spent the last few weeks using correlate to experiment with signal processing and I got strange results until I realised that I had to manually take the conjugate. It would also be good if the function did it since applying the conjugate to th

Hi, After my previous email, I have opened a ticket #1117 (correlate not order dependent) I have found that the correlate function is defined in multiarraymodule.c and that inputs are being swapped using the following code n1 = ap1->dimensions[0]; n2 = ap2->dimensions[0]; if (n1 < n
