Hi Daniel, Thanks for your suggestion. Could you open a JIRA issue with type "New feature" to register it ? The URL of our JIRA tracker is here: https://issues.apache.org/jira/browse/MATH
You will have to register in order to be able to create a new issue. regards, Luc ----- Mail Original ----- De: "daniel kuan" <[EMAIL PROTECTED]> À: dev@commons.apache.org Envoyé: Vendredi 11 Juillet 2008 12:23:43 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: [math] Fast Hadamard Transform I would like to suggest an addition of the fast hadamard transform to the following package: org.apache.commons.math.transform The class would be called: FastHadamardTransformer *1. A concise description of the new feature/enhancement.* The new feature will implement the fast hadamard transform. *2. References to definitions and algorithms.* Definition of the hadamard transform: http://en.wikipedia.org/wiki/Hadamard_transform#Definition Unfortunately, Mathworld does not provide a very detailed definition. http://mathworld.wolfram.com/HadamardTransform.html An elegant algorithm for the fast hadamard transform can be found here: http://www.archive.chipcenter.com/dsp/DSP000517F1.html *3. Some indication of why the addition/enhancement is practically useful.* The hadamard transform has applications in signal processing and data compression. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
