Note that some authors e g whittaker and watson 1990 p. 341 define without the leading factor of. 299 where is a confluent hypergeometric function of the first kind and is a gamma function. Revolutionary knowledge based programming language.

Erf satisfies the identities. The preeminent environment for any technical workflows. For certain special arguments erf automatically evaluates to exact values. Then i tried defining the function as exp log z 2 log erfc i z but this turns out to not be any faster than with automatic switching so it seems hard to speed this up except as daniel lichtblau suggests acl jul 24 11 at 23 46.

Erf z 0 z 1 is given by. Abramowitz and stegun 1972 p. The first few values extended by the definition for and 0 are given by. 0 i for large arguments.

I tried playing with setsystemoptions catchmachineunderflow false which however results in getting 0. Mathematical function suitable for both symbolic and numerical manipulation. Erf z is an entire function of z with no branch cut discontinuities.
