Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables. The error function is related to the cumulative distribution Φ {\displaystyle \Phi } , the integral of the standard normal distribution, by[2] Φ ( x ) = 1 2 + 1 The pairs of functions {erff(),erfcf()} and {erfl(),erfcl()} take and return values of type float and long double respectively.

Similarly, the En for even n look similar (but not identical) to each other after a simple division by n!. For more information, see Tall Arrays.TipsYou can also find the inverse standard normal probability distribution using the Statistics and Machine Learning Toolbox™ function norminv. Free Statistics Calculators version 4.0 cited in more than 1,300 scientific papers! Inverse Q Function Calculator The relationship between the inverse complementary error function erfcinv and norminv isnorminv(p)=(−2)×erfcinv(2p).For expressions of the form erfcinv(1-x), use the inverse error function erfinv instead.
