Consider the following code:
gauss[x_] := E^(-x*x)
sinc[x_] := Sinc[x]
Plot[gauss[x], {x, -5, 5}, PlotRange -> All]
Plot[sinc[x], {x, -5, 5}, PlotRange -> All]
Plot[Convolve[gauss[x], sinc[x], x, y], {y, -5, 5}, PlotRange -> All]
The first two plots look good, but it's been evaluating the final plot for an hour now, and I don't remember it working when I tried a few months ago. Incidentally, this doesn't evaluate to any close form:
Convolve[gauss[x], sinc[x], x, y]
What strategies can I try to get a plot of it?
