Define Method in Function File

To define a method in a separate file in the class folder, create the function in a file with

the .m extension. Do not use the method-end keywords in that file. Name the file with the

function name, as with any function.

In the myFunc.m file, implement the method:

function output = myFunc(obj,arg1,arg2)

...% code here

end

It is a good practice to declare the function signature in the classdef file in a methods

block:

classdef MyClass

methods

output = myFunc(obj,arg1,arg2)

end

...

end

Specify Method Attributes in classdef File

If you specify method attributes for a method that you define in a separate function file,

include the method signature in a methods block in the classdef file. This methods

block specifies the attributes that apply to the method.

For example, the following code shows a method with Access set to private in the

methods block. The method implementation resides in a separate file. Do not include the

function or end keywords in the methods block. Include only the function signature

showing input and output arguments.

classdef MyClass

methods (Access = private)

output = myFunc(obj,arg1,arg2)

end

end

In a file named myFunc.m, in the @MyClass folder, define the function:
