Follow-up Comment #5, bug #51512 (project octave): Not even that, but regexps can be tuned as well. Speed differenes between slow and fast regexps can be up to tens of percents. There's a bit of hidden literature bout it on the web and I think Rik knows a lot about it. I think the cellfun stuff you wrote could be much faster if the actual contents (is_bool_value) were written in C++ Be sure to benchmark with large spreadsheets (10,000 rows by -say- 1000 columns or so). _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?51512> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
