Rarely this function fails with the error that search direction does not reduce the function value and after raising an exception the execution stops. So i edited the code to not raise an exception but return the exitflag as -2. I mean what the exit flag is for if exceptions are being raised? I cannot afford a halt of execution. Please help. I want to copy paste that code, into a linesearch_editted().


Each one of you can help me. Please guys, anyone? I really need it urgently...
