Your solution is -1/2*I*sqrt(pi)*e^(-x^2)*erf(I*x) which Sage does produce correctly. But, Sage appears to be having trouble with erf(I*x). This should be a pure imaginary result, but Sage is not giving that.

Wolfram alpha plots your function nicely and also handles erf(I*x) well. (See [this link])(http://m.wolframalpha.com/input/?i=plot+-1%2F2Isqrt%28pi%29e%5E%28-x%5E2%29erf%28I*x%29+from+0+to+10&x=0&y=0)

Anyone have ideas on this?
