Unfortunately it involves a "solve for x" step that might make it useless to you. Patrick Top Steve Lionel (Intel) Tue, 04/15/2014 - 13:40 What you've found is entries for erfinv in Intel MKL. The th coefficient of this series can be computed as (17) where is given by the recurrence equation (18) with initial condition . Not a member?

Keep in mind this is code from the 386 era // Extract from package Numlib in the Free Pascal sources (http://www.freepascal.org) // LGPL-with-static-linking-exception, see original source for exact license. // Note Cody, Argonne National Laboratory, NETLIB/SPECFUN, March 19, 1990. That would be a nice contrib. –Warren P May 13 '11 at 12:27 I didn't initially since it isn't the inverse.

Tue, 04/15/2014 - 17:08 I did "kluge" up an inverse error function, for those that are interested. Inverse Error Function Matlab Therefore, I found another implementation based on rational function approximation. This is perfect :) –Mike Furlender May 12 '11 at 21:10 1 For the knowledgable: I'd be interested in a routine with a free license (BSD) btw, NR's example code It is quicker and more precise than the previous implementation from the old correlator.

Inverse Error Function Excel

Is it mathematically too complicated (it's been a while, too lazy to run now to our library to consult the math handbooks), or the methods approximate or involve more intricate details, The main computation evaluates near-minimax rational approximations from [1].

For the inverse of the error function, rational approximations accurate to approximately six significant digits are used to generate an initial approximation, Inverse Error Function C++ Practice online or make a printable study sheet. Inverse Error Function Calculator The Maclaurin series of is given by (15) (OEIS A002067 and A007019).

Iirc their code is based on Algol code from the (German) Handbuch der Automatik. –Marco van de Voort May 12 '11 at 16:03 Can you post the snippet? have a peek at these guys Original implementation in Fortan Code (look for MERFI subroutine) --Blanchet 17:50, 17 March 2008 (CET) Retrieved from "https://www.iram.fr/computer/wiki/widex/index.php/Inverse_Error_Function" Views Article Discussion View source History Personal tools Log in / create account You can use this from MKL but it is defined on arrays only. Top Steve Lionel (Intel) Tue, 04/15/2014 - 17:43 You need to select the "Use Intel Math Kernel Library" option under Fortran > Libraries. Inverse Error Function C++ Code

After all, one can get the same answers by using a DO LOOP.   And why they did that for the Error function and its complement, and not for their inverses, check over here Step-by-step Solutions» Walk through homework problems step-by-step from beginning to end.

I'm struggling to understand whether the VS2012/2013 implementation is for Nvidia accelerator only. Erfinv Approximation What makes a language "optimized" for a specific task? Best way to remove rusted steel bolts from aluminum parts How to avoid const cast for map access?

Could there ever be a fully solar powered airliner capable of transatlantic flights? 'idem hercle esset' meaning?

Math. As any statistician will tell you - just ask ! ! !   for example you would use the inverse when you know the probability of an outcome, and you want Looks like the Jedi math library needs lots of work. –Warren P May 12 '11 at 13:50 @David Wow, thanks a ton! Inverse Complementary Error Function If you can find c code great.

Should I list "boredom" as a reason for leaving my previous job in an interview? If I were doing this, I would translate the code from Numerical Recipes and get something accurate to double precision. –David Heffernan May 12 '11 at 13:48 Oops-- the this content Skip to main content Developer Zone Join today Log in DevelopmentOSAndroid*Chrome*HTML5Windows*Device2-in-1 & Ultrabook™Business ClientEmbedded SystemsIoTServer, Workstation, HPCTechnologyBig DataDual ScreenGame DevIntel® RealSense™ISA ExtensionsMachine LearningModern CodeNetworkingOpen SourceStorageToolsDeveloper TypeEmbedded SystemsGame DevMediaTechnical, Enterprise, HPCWebOSAll ToolsAndroid*HTML5Linux*OS
