Hello,
-- Can somebody tell me if in SciSmalltalk are some methods for finding the eigenvalues and eigenvectors of matrix?

Dear Natalia,
apparently there is something here : https://github.com/Cuis-Smalltalk/Cuis-Smalltalk/blob/master/Packages/LinearAlgebra.pck.st Did you check DHBNumerical package available in SciSmalltalk ? More documentation is needed ;-) Regards, On Mon, Apr 7, 2014 at 5:20 PM, Natalia Tymchuk <[hidden email]> wrote: > Hello, > Can somebody tell me if in SciSmalltalk are some methods for finding the > eigenvalues and eigenvectors of matrix? > Best regards, > Natalia > > -- > You received this message because you are subscribed to the Google Groups > "SciSmalltalk" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [hidden email]. > For more options, visit https://groups.google.com/d/optout. -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/ -- You received this message because you are subscribed to the Google Groups "SciSmalltalk" group.

You can also give a try to ConfigurationOfSmallapack. There might be a conflict or too with Complex numbers (SciSmalltalk forked from the original, which was extracted from Squeak), but it should not be too complex to merge.Nicolas 2014-04-07 17:26 GMT+02:00 Serge Stinckwich <[hidden email]>: Dear Natalia, You received this message because you are subscribed to the Google Groups "SciSmalltalk" group.

Hi Natalia, for _symmetric_ matrices there is jacoby's algorithm to calculate eigenvectors and eigenvalues in dhb. werner You received this message because you are subscribed to the Google Groups "SciSmalltalk" group.

Hello,
Can you tell me who is maintaining DHB project? Maybe it is possible to rename the asVector method to asDhbVector, because Moose overrides this method? Best regards, Natalia On Apr 7, 2014, at 11:36 PM, werner kassens <[hidden email]> wrote:
