MATLAB Programming

4 M-File Programming
7 Function elsewhere on the path
Finally, a function elsewhere on the path is selected. A function in a
directory that is toward the beginning of the path string is given higher
precedence.
Note Because variables have the highest precedence, if you have created a
variable of the same name as a function, MATLAB will not be able to run that
function until you clear the variable from memory.
Multiple Implementation Types
There are five file precedence types. MATLAB uses file precedence to select
between identically named functions in the same directory. The order of
precedence for file types is
1 Built-in file
2 MEX-files
3 MDL (Simulink® model) file
4 P-code file
5 M-file
For example, if MATLAB finds a P-code and an M-file version of a method in a
class directory, then the P-code version is used. It is, therefore, important to
regenerate the P-code version whenever you edit the M-file.
QueryingWhichFunctionMATLABWillCall
You can determine which function MATLAB will call using the which
command. For example,
which pie3
matlabroot/toolbox/matlab/specgraph/pie3.m
However, if p is a portfolio object,
