Does just what it said and just what I needed

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

20 Jun 2011 fminsearchbnd new improved bounded fminsearch algorithm Author: Ken Purchase Tootoonian, Sina

@Andy:

I got the same problem. The cause seemed to be that intrafun passes varargin to the function to m inimize, and if the latter function can't handle it, an error is generated.

The workaround I found was to let my function accept varargin as a dummy argument e.g. If my function was f = @(x) x^2, to change it to f = @(x,varargin) x^2. When this is done, the new function can handle the varargin passed in through intrafun, and no error results.

Hope this helps!

Has anybody been able to run this function in a parfor loop?

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.
