Some documentation and preferably an example would be very helpful - I'm trying to reverse engineer how to use this. Thanks.

good job and thank you very much

I was going to use this code to fit Gaussians to a known curve by minimizing the known - fit residual. I tried for 3 and 4 Gaussians, meaning 9 or 12 variables. This newer code fails giving the error:

Too many input arguments.

Error in ==> fminsearchbnd>@(x,varargin)fun(xtransform(x),varargin{:}) at 233
    intrafun = @(x, varargin) fun(xtransform(x), varargin{:});

Error in ==> fminsearch at 205
fv(:,1) = funfcn(x,varargin{:});

Error in ==> fminsearchbnd at 264
[xu,fval,exitflag,output] = fminsearch(intrafun,x0u,options,varargin);

The original code by John D'Errico works perfectly.

I like the changes that Ken has made. They clean up the code nicely. Not much to say other than - well done.

Thanks John - I realize I shipped it with a few bugs. I'll update it when I get to the office Monday.

I'll get to a careful review of this asap, but until I do, I'll note that the optimization toolbox is listed as a requirement. Since fminsearch is part of Matlab, that toolbox should not be necessary. Until then, it looks like Ken has found some things to clean up in my code. If so, well done.
