I have a class called "Wavefront" with a method called "ToMAT". Let W be an instance of a Wavefront object. I want the behavior of W.ToMAT('filen... 12 May 2010 16:58

Cell mode turned on, but code folding isn't working
Using R2010a and R2009b... I have a large script m-file (~188k lines) auto-generated by COMSOL Multiphysics (a finite element solver). 99.99% of those lines are oddly formatted COMSOL data (which I can't easily read in from a mat file). I would be content to wrap these data sections in cell tags (%%) and fold ... 12 May 2010 13:36

fminsearch and multiple inputs to function
I am editing some legacy code in which fminsearch is implemented as, [x, fval] = fminsearch('myfun', x, options, arg1, arg2, arg3) ; where 'myfun' is the name of a saved function myfun.m that takes input arguments x, arg1, arg2, and arg3, each of which are vectors (though most with just one element). myfun.m retur... 12 May 2010 15:50
