Subject: The error function... From: Lars Struen Imsland Date: 4 May, 2001 15:55:50 Message: 1 of 9 Reply to this message Add author to My Watch List View original format Flag as spam I would like to evaluate an integral on the form (a > 0) \int_0^x e^{a t^2} dt in error function Matlab. This is almost the error function (erf.m). If erf would allow complex arguments, I could write .5*sqrt(pi)*erf(sqrt(-a)*x)/sqrt(-a); But it does not. If the imaginary error function existed, I could have used that. In maple: int(exp(a*t^2),t=0..x); erf(x sqrt(-a)) sqrt(Pi) 1/2 ------------------------ sqrt(-a) a := .1; x := 2; a := .1 x := 2 int(exp(a*t^2),t=0..x); 2.301967758 .5*erfi(sqrt(a)*x)/sqrt(a)*sqrt(3.1415926); 2.301967739 Lars Subject: The error function...
