Erfinv python

WebDescription Y = erf(X) returns the value of the error function for each element of real array X. Y = erfc(X) computes the value of the complementary error function. Y = erfcx(X) computes the value of the scaled complementary error function. X = erfinv(Y) Elements of Ymust be in the interval [-1 1]. The function erfinvsatisfies for and . WebThe inverse error function erfinv is defined as the inverse of the error function, such that Tips For 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 small number and may be rounded down to 0.
