Calling Functions
Passing Function Handles
The MATLAB function handle has several uses, the most common being
a means of immediate access to the function it represents. You can pass
function handles in argument lists to other functions, enabling the receiving
function to make calls by means of the handle.
To pass a function handle, include its variable name in the argument list of
the call:
fhandle = @humps;
x = fminbnd(fhandle, 0.3, 1);
The receiving function invokes the function being passed using the usual
MATLAB calling syntax:
function [xf, fval, exitflag, output] = ...
fminbnd(fhandle, ax, bx, options, varargin)
.
.
.
113 fx = fhandle(x, varargin{:});
Passing Arguments in Structures or Cell Arrays
Instead of requiring an additional argument for every value you want to pass
in a function call, you can package them in a MATLAB structure or cell array.
Passing Arguments in a Structure
Make each input you want to pass a separate field in the structure argument,
using descriptive names for the fields. Structures allow you to change the
number, contents, or order of the arguments without having to modify the
function. They can also be useful when you have a number of functions that
need similar information.
