Orbit response matrix bug in elegant 20.0

Post by petrenko » 16 Jan 2009, 01:05

Orbit response matrix fitting does not work in new elegant 20.0:

This is the responseMatrixFit4 example:

I've confirmed this bug and am looking into it. It seems only to affect response matrices during optimization, which unfortunately wasn't covered by the regression tests.

Have you seen it in any other cases?

I've determined that this will also affect runs with use_perturbed_matrix=1 in the &correct command and that request repeated response matrix inverse computation via use_perturbed_matrix in the &correct command.

A fix will be available shortly.

Version 20.0 has been updated on the web to fix this bug.

Thanks to Bob Soliday for lightning-fast turnaround on this.

Mike,

I downloaded version 20.0 binary on January 26. I see the bug still. In the &correct command, if I set use_perturbed_matrix=1, this fails. It worked with version 19.

Ray,

I tried your files and they worked without any errors. Can you check that you have the right version installed? If you just run without any arguments, you should get a message starting with "This is elegant 20.0.3". If it says 20.0.2, you are still using the previous release.

Mike,

I am using 20.0.3. Try this file. The only difference with the previous is that use_perturbed_matrix=1. This breaks it.
