I changed the version number in CVS earlier today to be 2.9.5+ and the following test from cell2mat.m is now failing: %!test %! if ([1e6,1e4,1] * str2num (split (version, '.')) > 2010064) %! assert (cell2mat (D), F); % crashes octave 2.1.64 %! endif Do we really need the version number test here? If there is a need to compare version numbers, then perhaps we should have a function to do it that can handle things like 2.9.5+ or 2.9.5+SVN-serial-number (or similar). Comments?
When deploying software which depends on Octave I do not want to force people to upgrade. In order to support older versions there will sometimes be a need to compare version numbers. Alois' NaN and TSA packages in octave-forge/extra are designed to support multiple versions of octave and matlab if you want a real world example of the sort of tests that are needed.* - Paul
