Did you know?
WebIf x < –1 or x > 1, or if x is complex, then erfinv (x) returns NaN. Algorithms The toolbox can simplify expressions that contain error functions and their inverses. For real values x, the toolbox applies these simplification rules: erfinv (erf (x)) = erfinv (1 - erfc (x)) = erfcinv (1 - erf (x)) = erfcinv (erfc (x)) = x WeberfinvSP (x) = (xp1(w), w ≤ w1 central region xp2(s), w1 < w tail region where w = − log(1−x2), s = √ w, and p1(w) and p2(s) are two polynomial functions. The motivation for …
WebThis function accepts real arguments only. If you want to compute the inverse error function for a complex number, use sym to convert that number to a symbolic object, and then … WebFor expressions of the form erfinv(1-x), use the complementary inverse error function erfcinv instead. This substitution maintains accuracy. When x is close to 1, then 1 - x is a …
