How MATLAB Handles Undefined Methods
If your MATLAB® command invokes a nonexistent method on a Java® object, MATLAB looks for a function with the same name. If MATLAB finds a function of that name, it attempts to invoke it. If MATLAB does not find a function with that name, it displays a message stating that it cannot find a method by that name for the class.
For example, MATLAB has a function named
size, and the Java API
java.awt.Frame class also has a
method. If you call
size on a
Frame object, the
size method defined by
java.awt.Frame is executed.
However, if you call
size on an object of
java.lang.String, MATLAB does not find a
size method for this class. Therefore, it
executes the MATLAB
size function instead.
text = java.lang.String('hello'); size(text)
ans = 1 1
When you define a Java class for use in MATLAB, avoid giving any of its methods the same name as a MATLAB function.
