Java Error Function

The accuracy of the Commons-Math implementation is assessed by comparaison with high precision values computed with the Maxima Computer Algebra System. I just needed to download the binary files and add it as a .jar. Replace custom functions, leave built in functions untouched? Why don't major research institutions systematically publish their subscription fees to scientific journals? this content

Why don't quaternions contradict the Fundamental Theorem of Algebra? The implementation uses either erf(double) or erfc(double) depending on which provides the most precise result. Interval Values tested Average error Standard deviation Maximum error -5 < x < -4 x[i] = i / 1024, i = -5119, ..., -4097 0.49 ulps 0.57 ulps 3.0 ulps -4 Skip to content Ignore Learn more Please note that GitHub no longer supports old versions of Firefox.

Handlers for checkboxes to select various map features How can I nominate games on Steam? static double erf(doublex1, doublex2) Returns the difference between erf(x1) and erf(x2). java eclipse apache import static-libraries share|improve this question edited Apr 25 '13 at 17:50 Luiggi Mendoza 65k763135 asked Apr 25 '13 at 17:49 Beetlejuice 206 add a comment| 1 Answer 1 erfc public staticdoubleerfc(doublex) The complementary error function.

The accuracy of the Commons-Math implementation is assessed by comparison with high precision values computed with the Maxima Computer Algebra System. It is defined as: erf(x) = ∫0x e-t2dt The complementary error function, denoted erfc, is defined as erfc(x) = 1 - erf(x). The problem is that I can not use it. All rights reserved.

But unfortunately, I can not include the library and use it neither because what I download from : http://commons.apache.org/proper/commons-math/download_math.cgi is not a .jar Does someone know how to "install - use"

We recommend upgrading to the latest Safari, Google Chrome, or Firefox. erf(x) = 2/√π 0∫x e-t2dt This implementation computes erf(x) using the regularized gamma function, following Erf, equation (3) The value returned is always between -1 and 1 (inclusive).
