this code was working fine in ocatave untill update ubuntu from 14.04 to 16.04, it gives me this error

[Signal, Header] = sload('../data/A01T.gdf');

** On entry to DGEMV parameter number 3 had an illegal value

SLOAD: mexSLOAD('../data/A01T.gdf') failed - the slower M-function is used.

error: getfiletype: exception encountered in Fortran subroutine dgemv_

error: called from getfiletype at line 122 column 7 sload at line 668 column 4

  • Did you do a clean install of 16.04 or an upgrade?

  • So, not a clean install. Mmm, it seems from here that both Trusty and Xenial are using the same version. For the lack of alternatives, you could purge octave, and install again, or do that for the sload and biosig packages you have.

  • Ok, then somehow you installed manually. Save everything you want from octave (configs, scripts, etc), and then delete manually. Can you find the location of octave? Maybe usr/local/? Or in your home folder? Use Catfish File search to look for every octave file. There must be a hidden config file in your home folder too. Probably .octave/. Enable hidden files with Ctrl+H. Once you eliminate everything, reinstall. Let's see how it goes from there.
