Dear Wiki user, You have subscribed to a wiki page or wiki category on "Jakarta-commons Wiki" for change notification.
The following page has been changed by PhilSteitz: http://wiki.apache.org/jakarta-commons/MathWishList ------------------------------------------------------------------------------ A list of feature requests made by Commons-Math users, contributors, and committers. These requests will be considered when deciding on new functionality for future releases. At any time, additional feature requests can be added simply by editing this page. * Add remedian statistic - [http://www.agoras.ua.ac.be/abstract/Remrob90.htm The Remedian: a Robust Averaging method for Large Data Sets] - * Add population variance and standard deviation statistic. * Add alternative pseudo-random number generators (PRNGs) * "implement good random number generators, e.g., like those described in ''Numerical Recipes'' or Knuth". -- AlChou * I highly recommend working with Paul Houle [http://www.honeylocust.com/RngPack/] to get these random number generators integrated into the math library. He has stated to me in the past that he is willing to relicense them under the Apache license. As well I beleive that with the BSD being compatable with Apache licensing, there would be little stopping us from integrating them ourselves as a derivative work. - Mark Diggory - * Support PRNG-pluggability throughout the random package - COMPLETED * Investigate alternative methods for generating values from discrete distributions [http://www.jstatsoft.org/v11/i03/] - * Add sparse matrix implementation. [http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&by=thread&from=736078] + * Add sparse matrix implementation. [http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&by=thread&from=736078] * Add Vector implementation (RealVector would extend RealMatrix) - * Add submatrix accessors - [http://issues.apache.org/bugzilla/show_bug.cgi?id=30896] * Develop Genetic Algorithms Framework [http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&by=thread&from=882939] * Resampling [http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&by=thread&from=582054] * Applied-mathematical/Mathematical-physics algorithms? - Henri Yandell @@ -22, +19 @@ * "Rolling" statistics with large windows but limited storage [http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&msgNo=41870] * I don't understand; we already have some storage-less statistics. What am I missing from the post you refer to? -- AlChou * Oh, I remember now that with the standard deviation algorithm I researched, in order to maintain a '''rolling window''', it would have to store all the data in the window so it could delete the least recent one while adding the most recent one. Sorry for the denseness. -- AlChou - * Provide FFT's. -- AlChou - * do full implementation like [http://www.fftw.org/ FFTW] -- AlexGraesser * [[Anchor(summerofcode)]] Numerical Enhancements (Summer of Code Proposal) * Du Li * an approximation package, with an emphasis on the support for B-splines, which is used to approximate curves in general, given a set of points on the curve. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
