How to pass arrays to class properly?

1 次查看(过去 30 天)
I have 3 arrays
a=[[1;2;3],[4;5;6],[7;8;9]]
b=[[3,2,1],[6,5,4],[9,8,7]]
c=[3 6 9]
inst=myclass;
inst.myfunc(arr1, arr2, arr3);
and I delivered it to my class
classdef myclass
properties
a;
b;
c;
end
methods
function obj=myfunc(obj, arr1, arr2, arr3)
obj.a=arr1;
obj.b=arr2;
obj.c=arr3;
end
end
end
the result says
myclass.a=[]
same for the other properties
why this happens? and how to fix it?
I had thought that this is something to do with class instructor
so I made empty class constructer and added it to methods
function obj=myclass(obj)
end
and fixed 'inst' too
inst=myclass();
same error had occured.

The class you defined is called value class in MATLAB. The didn't directly modify the instance of the class. You need to assign it yourself
inst = inst.myfunc(arr1, arr2, arr3);
Your current code will also work, if you define your class as handle class, in that case
classdef myclass < handle
properties
a;
b;
c;
end
methods
function obj=myfunc(obj, arr1, arr2, arr3)
obj.a=arr1;
obj.b=arr2;
obj.c=arr3;
end
end
end
