This seems to be a very useful mathematical processor. Unfortunately the 'fsolve' function seems not to work. It seems always to return the given starting point value and a status of -1. Is this a known issue? Does anyone have this working under FreeBSD 5.x? I see some reference to problems with fsolve when this was first converted to a runtime loadable .oct module rather than built in to the octave core. However I wonder whether the problem may actually be in one of the library ports on which octave depends; I'm thinking particularly of the libraries created by the atlas port. Does anyone have any information, suggestions, ideas or fixes for this problem? I've explored the internet with respect to this problem but not turned up anything useful. Any response would be appreciated. Malcolm
