[Gretl-users] Re: Error executing the convolve.inp script file

I mean if that example script used to work and cmult() is still being dragged around, then I guess the script should ideally still work? cmult() still works, given old-style (pre-2020) complex matrices as input. The trouble with the outdated convolve script was that fft() now produces a new-style (proper) complex result. I'd say that cmult() and cdiv() are both pretty much useless at this point. You could cook up old-style complex matrices and feed them to these functions as arguments, but why would anyone want to do that?
