Error: File: cftool.m Line: 355 Column: 33 Unexpected MATLAB operator
显示 更早的评论
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.

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);
