如何在matlab gui中实现mvc设计的想法 [英] how to implement the idea of mvc design in matlab gui's
问题描述
请在一个项目上开发一个可视化工具，以便在matlab中使用mvc设计来分析数据。但是我遇到的问题是，新的编程和matlab是第一个真正的程序设计。 ive几乎完成了代码，但我害怕他们没有办法在mvc设计模式，所以我需要改变这一点。
please am a student working on a project to develop a visualization tool to analyse data using an mvc design in matlab. but the problem im having is that im new to programming and matlab is the first real programing im doing. ive pretty much done the codes but i fear they are no way in an mvc design pattern so i need to change this.
真的很欣赏尽可能多的引用，以链接我有用的材料，因为我无法在matlab中找到任何mvc，或者可能是在matlab中实现mvc的示例代码帮助我了解我如何可以做我的，目前和做这样的事情，数据是一个结构与.Name和.Data的文件。函数/方法datcorrCoef和datCorrSum是我创建的函数，它接受我的数据对象作为参数
would really appreciate as many imputes as possible to link me up with useful materials as i cant find any for mvc in matlab or may be exemplar codes that implement mvc in matlab to help give me an idea of how i can do mine, presently and doing things like this, where data is a structure with fileds for .Name and .Data. the functions/ methods datcorrCoef and datCorrSum are function i have created that accept my data object as arguments

其中我在控制器中再次具有与我的数据对象一起操作的其他功能;真的很沮丧的整个事情！如果对我的问题的描述不够清楚，请让我知道，以便您可以帮忙。谢谢
where i again have other functions that operate with my data object here in the controller; really frustrated about the whole thing!! please let me know if im not being clear enough about the description of my problem so you can please help out. thank you
推荐答案
对于MVC，您需要正确的对象定向。 MATLAB中的OO可以在较新的版本中使用，您可以像在Java中做MVC那样做。但是在MATLAB中它并不感觉（所以我不认为你的教练是这样的），因为在大多数简单的情况下，对于复杂/大型UI的 MATLAB太慢了，在某些情况下会出现性能问题。
For MVC you need proper Object-Orientation. OO in MATLAB is available in the newer versions, you can just do it like you would do MVC in Java. But it does not "feel" right in MATLAB (so I do not think your instructor meant this) because it would be an overkill in most simple cases and for complex/large UI's MATLAB is too slow and has performance issues in some scenarios.
否则可以使用嵌套函数在CS）。关闭一些OO功能可以模拟。唯一的问题是一切都必须保留在一个m文件中。
Otherwise you can use nested functions (closures in CS). With closures some OO functionality can be "emulated". The only problem is that everything has to stay in one m-file.
- 模型：嵌套作用域变量（此处命名为this）
- 查看：uicontrols（和其他ui元素）
- 控制器：回调
这是一个非常基本的例子，只需填写您的模型数据并查看ui：
Here is a very basic example, just fill it with your model data and view ui's:
function mvc_test()
//% THIS is nested scope variable
this.model = getModel();
this.view = getView();
//% create model
function model = getModel()
model.data1 = 1;
end
//% create view
function view = getView()
view.hfig = figure();
view.hbtn = uicontrol( 'style', 'push', 'string', 'click me', 'callback', @btn1_cb );
end
//% controller
function btn1_cb(varargin)
this.model.data1 = this.model.data1 + 1;
set( this.view.hbtn, 'string', num2str(this.model.data1) );
end
end
