fitting code from cftool

I used a cftool to create a code to fit my data. I want to use linewidth of 2 points. when I used

figure( 'Name', 'untitled fit 1' );

h = plot( fitresult2, 'b'); h.LineWidth=2;

I got an error of

Warning: Struct field assignment overwrites a value with class "double". See MATLAB R14SP2 Release Notes, Assigning Nonstructure Variables As Structures Displays Warning, for details.

and the linewidth does not change. I need it for my lab work. any help will be appreciated.

What release are you using? If you're using a release prior to release R2014b, you will need to use set to change the properties of the line returned by plot rather than the dot notation that will only work in release R2014b or later.
