Constant already used When creating function handle

I am trying to create a handle for a Function, I received two errors:

Error: 
Expression or statement is incomplete or incorrect.

Error: "p1" was previously used as a variable, conflicting with its use here as the name of a function or command.

I am attempting to create a new function handle for an existing function created using the curve fit tool.

The syntax I use is

x = @fun;

will someone please correct this command?

If fun is already a function handle, then you can try

x = fun;

or

x = @(varargin) fun(varargin{:})

Hello, is varargin used to satisfy the constants used? The function was generated by the curve fit toolbox. Your original suggestion is what I used and prompted the error.

Thank you.

You used

x = @fun

rather than

   x = fun

We need to see more of your code.

I suspect you might need to read http://www.mathworks.com/help/matlab/math/parameterizing-functions.html

Yes this works fine and generates a new X handlehowever I get a simple error when I try to use fplot. To related and may I plot this handle?

Please show a SMALL, self-contained example (that people can execute as part of their investigation) and the FULL text of the error message you receive when you execute that self-contained example.
