Okay, here's the story: I wanted to plot a Fourier transform of a Gaussian that is truncated (mulitplied by unit step function). Using "integral", I got an answer that looked nice, but contained an error function with an imaginary argument. Because that error function couldn't be evaluated, I couldn't plot. So, that brings up the question: is there a nice way to evaluate the error function of an imaginary number (or more generally a complex number) in Sage?
