如何在 Matlab 中使对象在其 class 内可访问？

Question

在这个 class 中，我怎样才能让 fig 对象在其 class 中提供自己的相关属性，例如 my_function;

classdef Test
    properties
        a
        b
    end

    methods
        function obj = Test(a, b)
            obj.a = a;
            obj.b = b;
        end  
        function [] = my_function(obj)
            fig.Name   %%% here fig object is needed
            disp('done!')
        end  
        function [fig] = my_figure(obj) 
            fig = figure();
        end
    end
end

Answer 1

您需要将 fig 存储为 class 的属性，然后从 my_function 中访问 fig 属性当前实例。作为旁注，如果您希望能够通过引用传递您的 class 实例，您需要子 class MATLAB 的 handle class：

classdef Test < handle
    properties
        fig         % Setup a property to hold the handle to the figure
        a
        b  
    end

    methods
        function obj = Test(a, b)
            obj.a = a;
            obj.b = b;
        end  

        function [] = my_function(obj)
            % Access and modify the figure handle as needed
            obj.fig.Name = 'Name';
            disp('done!')
        end  

        function [fig] = my_figure(obj) 
            fig = figure();

            % Store the handle in the "fig" property of the class
            obj.fig = fig;
        end
    end
end
