如何从 uideditfiled 命令创建的字段中获取值？

问题描述

我是新的 matlab 应用程序设计器应用程序。我创建了一个数字字段，然后我要求用户输入，然后我根据用户输入自动创建数字字段。 （图2）。我如何读取创建字段中的值？ 另外，是否有不同的方法可以自动创建字段并作为组件添加。

classdef app8 < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
    UIfigure           matlab.ui.figure
    NumEditFieldLabel  matlab.ui.control.Label

        for i = 1:app.NumEditField.Value
        eval(sprintf('app8.ef%d = uieditfield(app.UIfigure,"numeric")',i));
        eval(sprintf('app8.ef%d.Position = [180,350 - %d,31,22]',i,37*i))

        app.UIfigure = uifigure('Visible','off');
        app.UIfigure.Position = [100 100 640 480];
        app.UIfigure.Name = 'MATLAB App';

        % Register the app with App Designer
        registerapp(app,app.UIfigure)
        if nargout == 0
            clear app
        end
    end
    % Code that executes before app deletion
    function delete(app)
        % Delete UIfigure when app is deleted
