ORDEIG fails

8 років тому • оновлено 8 років тому • 1

Hi Pavel,

I hope you are doing fine?! I'm running Advanpix Version 3.9.4 Build 10481 on Windows and ORDEIG crashes MATLAB 2015B with a "FatalException" on the following problem:

KK = [ mp('1.2856486930664507983834710103110410e+00'), mp('0.0000000000000000000000000000000000e+00') ;

mp('0.0000000000000000000000000000000000e+00'), mp('1.2856486930664507983834710103110410e+00') ];

HH = [ mp('1.4142135623730976590195496100932360e+02 - 1.4142135623730959537169837858527899e+02i'), mp('1.2325951644078309459558258832543535e-32 + 0.0000000000000000000000000000000000e+00i') ;

mp('0.0000000000000000000000000000000000e+00 + 0.0000000000000000000000000000000000e+00i'), mp('1.4142135623730976590195496100932360e+02 + 1.4142135623730959537169837858527899e+02i') ];

ee = ordeig(HH,KK);

When calling ordeig(double(HH),double(KK)), everything works fine. Please see below for my mp.Info output and the crash report.

Cheers, Stefan

Hi Stefan,

Thank you for using the toolbox!

This bug was fixed long time ago - please use newer version of toolbox.

One year has passed - 3.9.4 is an ancient fossil by now!!!

There is another reason to switch to newest version of toolbox - now it has full-featured EIGS with the support of all modes ('SM', etc.) and variants (including when matrix is supplied as operator). Generalized problems are supported as well.

The only (temporary) downside - now EIGS is written in M-language and quite slow. We are working on this and it will be much faster soon.

I highly recommend you to test new version.
