palm_error.m

function palm_error(ME)
% Print error messages somewhat similarly as it would
% natively in Octave or Matlab, but does not necessarily
% crash the calling function, such that PALM can exit
% cleanly even if there are errors.
%
% Usage:
% palm_error(ME)
%
% - ME : MException object (or a struct with
%        similar fields).
