Hi there! I am using Octave 2.9.9 and the bfgsmin works well. However, the same code does not work when I try to run it in Octave 3.0.1 - the error message is "warning: bfgsmin: failure, exiting. Try different start values?" even though I am using the same starting values.
Is there any difference between the bfgsmin versions? If not, what is the problem? Thanks in advance Marcio Diniz
