I have the main script file and a class file. In the class file, I have two functions (funk and funk1) and in the functions, I have several variables which I call from the main script.
However, if I have a variable in one function of the class, how can I use the same variable in another function of the class (it could be both as input or output)? Below is an example.
classdef ga_clas
% The battery constraints
properties
%Property1
end
methods (Static)
function[a,b,c,d]=funk(f,g,h,i,j,k,l)
% The value of all input are from main script
for j=1:24
g(j)=f(j)+k(j)
end
% g is the variable in the class that can be used as output in another function, I'm not sure whether I'm using it correctly or not.
end
function [g, M, N]=funk1(t,y,u,i,f)
% and If I have to use variables from the previous function (funk1) which could be input or output then can I use it here?
end
end
end
There's two ways of doing this.
1: as Cris Luengo mentioned, you can return g. This would look something like this:
function[a,b,c,d,g]=funk(f,g,h,i,j,k,l)
for j=1:24
g(j)=f(j)+k(j)
end
end
Then, when you call funk you would do:
main
%other code
[a, b, c, d, g] = ga_class(f, g, h, i, j, k, l)
2: set g as a property of ga_class:
properties
g = [] %i don't know what type g is could be assigned as 0 or whatever it's type is
end
methods (Static)
function[a,b,c,d]=funk(self, f,g,h,i,j,k,l)
%self being passed in would be an instance of ga_class
for j=1:24
g(j)=f(j)+k(j)
end
self.g = g %this assigns it into this method's properties
end
Then, later you can call:
ga_class.g
You most likely want the first way, but it is possible to do it the second way.
