Follow-up Comment #15, bug #44310 (project octave): Mike: I thought about this a bit more: How much work is it for a C++ person to fix this by use of replacing return log ((1.0 + x) / (1.0 - x)) / 2.0; with return catanh( x ); If it is not too much work to get all the declarations straight, it would be good to get this into 4.0. It is the following: 1. Regression 2. Incorrect result 3. Incompatible with Matlab these formally qualify it as a blocker. I f I could help more I would. If you tell me what to do, I will test it. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?44310> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
