I think it is an issue with your MATLAB path. Did you follow the directions exactly as spelled out in the MATPOWER installation instructions? Did you maybe add all subdirectories of the MATPOWER directory? You don't want to have the @opf_model directory in your MATLAB path, only it's parent directory.
And just to be clear the comment from José about using older versions of Matlab appears to be related to PSAT. It certainly does not apply to MATPOWER, which should work just fine on all recent versions of Matlab (and Octave, for that matter). -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Dec 17, 2012, at 8:06 AM, José Roberto Camacho <[email protected]> wrote: > Dear Sir, > > It seems you have a problem on the matlab optimization toolbox.
