% Get default command line output from handles structure

varargout{1} = handles.output;

Input Arguments

The output function has three input arguments: hObject, eventdata, and

handles. They are the same as described in “Input Arguments” on page 8-13.

Output Arguments

The output function has one output argument, varargout, which it returns to

the command line. By default, the output function assigns

handles.output to

varargout. So the default output is the handle to the GUI, which was assigned

handles.output in the opening function.

You can change the output by:

• Changing the value of

handles.output. It can be any valid MATLAB value

including a structure or cell array.

• Adding output arguments to

varargout.

varargout is a cell array. It can contain any number of output arguments.

By default, GUIDE creates just one output argument,

handles.output. To

create an additional output argument, create a new field in the

handles

structure and add it to

varargout using a command similar to

varargout{2} = handles.second_output;
