how to call a private function in private function？
显示 更早的评论
APP DESIGNER methods (Access = private)
Inside the private function is the following statement to call another private function, ECEFtoECI
[B] = ECEFtoECI(app, A);
%When running, an error message is displayed indicating that the variable "app" cannot be recognized.
[B] = ECEFtoECI(JD(i), A);
%If this is the case, an error message is displayed indicating that ECEFtoECI cannot be found

function definition
function [B] = ECEFtoECI(app, A) % app as default first arg
...
end
function call (leading app.*)
[B] = app.ECEFtoECI(A)

The calling function has to have app as an argument .
function callerOfECEFtoECI(app,others)
ret = app.ECEFtoECI()
end

It is my understanding that you want to call a private function within a private function. Since I am not sure where exactly the object is being instantiated, there can be two scenarios where this will work.
Case 1: Calling the first private function from the constructor whose access level is public.
classdef MyClass
methods (Access = private)
function output1 = privateFunction1(obj)
output1 = obj.privateFunction2(A); % calling another private function
disp(output1);
end
function output2 = privateFunction2(obj,A)
output2 = A+35;
end
end
methods
function obj=MyClass()
obj.privateFunction1();
end
end
end
Case 2: Defining a public or a static function which can instantiate objects of the class (factory function).
classdef MyClass
methods (Access = private)
function output1 = privateFunction1(obj)
A=3;
output1 = obj.privateFunction2(A); % calling another private function
disp(output1);
end
function output2 = privateFunction2(obj,A)
output2 = A+35;
end
end
methods (Static)
function obj=createInstance(obj)
obj=MyClass();
obj.privateFunction1();
end
end
end
An instance of the class can be created by calling the static method.
obj=MyClass.createInstance();
You can refer to the method syntax documentation for more information about different types of methods and the syntax used to define them.
