Matlab策略模式

策略模式的意图是定义一系列算法，把它们一个一个封装起来，并且使它们可以互相替换。通常每个策略算法不可抽象再分。本人仿照https://www.runoob.com/design-pattern/strategy-pattern.html所给的例子，用Matlab代码对其进行实现

Strategy.m

classdef Strategy < handle

    methods(Abstract)

        doOperation(~,~,~);

    end

end

OperationAdd.m

classdef OperationAdd < Strategy

    methods

        function res = doOperation(~,num1,num2)

            res = num1 + num2;

        end

    end

end

OperationMultiply.m

classdef OperationMultiply < Strategy

    methods

        function res = doOperation(~,num1,num2)

            res = num1 * num2;

        end

    end

end

Context.m

classdef Context < handle

    properties

        strategy

    end

    methods

        function obj = Context(strategy)

            obj.strategy = strategy;

        end

        function res = executeStrategy(obj,num1,num2)

            res = obj.strategy.doOperation(num1,num2);

        end

    end

end

测试代码：

context = Context(OperationAdd());

disp("2 + 3 = " + context.executeStrategy(2, 3));

context =Context(OperationMultiply());

disp("2 * 3 = " + context.executeStrategy(2, 3));
