question about pdgbtrf

[stansy]

Hi,

Where I could find a manual and / or examples of the use of the function pdgbtrf?

Function returns me the error:

{... ...}: On entry to   parameter number 9 had an illegal value  

 PDGBTRF: auxiliary storage error

info: -9;

Thanks

Stan

There is an example driver at http://www.netlib.org/scalapack/explore-html/de/d37/pdgbdriver_8f_source.html . Since you did not show the calls to Scalapack that caused an error, I cannot comment on what could have gone wrong. The Scalapack documentation is available at http://www.netlib.org/scalapack/#_documentation .

Thank you very much for the useful links

Have you ever tried to invoque this from a C code?

Thanks.

For a long time I use only C++. I do not remember what kind of mistake I made. But I've never had more problems using function  pdgbtrf based on the attached example driver by Macej4.
