Error: File: cftool.m Line: 355 Column: 33 Unexpected MATLAB operator

I recently downloaded and installed the curve fitting toolbox. When I open the toolbox in Matlab (by typing cftool), there is an error.

??? Error: File: cftool.m Line: 355 Column: 33 Unexpected MATLAB operator.

Line 355 of the cftool.m file is: function adjustLayout2Callback( ~, ~ )

Does anybody know how I can solve this error?

What version of Matlab do you have?

I'm guessing its R2008b or earlier?

If I recall thats when the ~ was introduced to replace unused input/output arguments.

It looks like the cftool you have downloaded is for a more recent version.

Thanks for the answer.

I'm using R2009a.

And now I see, the version I've downloaded is R2010a.

Do you know if it is possible to make it work, or not?

[Robert Cumming]

dont know - check release notes to see whats updated (I dont have 2010).

[Walter Roberson]

The toolbox versions must match the base software version.

All that those tildes mean is the input arguments are not used in the function. Try changing the code to this:

function adjustLayout2Callback(varargin)

If you get a function like this:

function func(A,~,H)

just replace the ~ with 'junk' (no quotes of course.)

Also, for output arguments, you will sometimes see:

[~,I] = sort(A);

You can replace this with:

[I,I] = sort(A);

or,

[junk,I] = sort(A);
