In my personal computer I have many things installed and I was using the convolution command (conv and conv2) with no problems.
But yesterday I was teaching and I have no sudo access on the class room. The students were trying to use conv and getting an error saying that FFTW was missing. I'll only have sudo access there to test in on Monday. But my guess is that I need to install libfftw3, correct? Is this a bug? Since conv is part of the base I guess it should have libfftw3 as a dependency on Ubuntu, right?
