如何在已编译的.NET程序集中使用Matlab对象? [英] How can I use Matlab objects in compiled .NET assemblies?

问题描述

我有一个基本的Matlab类，我想在C#中实例化.

I have a basic Matlab class which I want to instantiate in C#.

classdef MyClass
    properties
        Value
    end

    methods
        function obj=MyClass(v)
            obj.Value = v;
        end

        function display(obj)
            disp(obj.Value);
        end
    end    
end

然后将其内置到.DLL文件中，并与关联的Matlab命名空间(MathWorks.MATLAB.NET.Arrays，MathWorks.MATLAB.NET.Utility)一起导入C#项目中.

This is then built into a .DLL file and imported in a C# project along with the associated Matlab namespaces (MathWorks.MATLAB.NET.Arrays, MathWorks.MATLAB.NET.Utility).

在C#端，我试图以此构建此类的实例:

On the C# side, I am trying to build an instantiation of this class thus:

        Untitled2.MLTestClass matlab = new Untitled2.MLTestClass();
        MWCharArray input = new MWCharArray("Initial");                       
        MWArray[] result = matlab.MyClass(1, input);

在最后一行代码的末尾，result.Length = 1并且result [0] = null.我以某种方式期望以某种方式获得对新创建的Matlab对象的引用.我在想，这有可能吗?如果是的话，那该如何完成呢?如果没有，有没有办法解决? (我基本上有一个用C#编写的GUI组件，我不想将其集成到Matlab中，反之则相反).

By the end of the last line of code, result.Length = 1 and result[0] = null. I was somehow expecting to obtain the reference to the newly created Matlab object somehow. I was wondering, is this even possible? And if yes, then how can this be accomplished? If no, is there a way around it? (I basically have a GUI component written in C# which I don't want to integrate in Matlab, but rather, the other way round).

推荐答案

它是

It is not possible to use Matlab classes inside .NET assemblies. There are numerous workarounds:

1. 将变量定义为 global ，并使用几个包装其方法的函数来访问它
2. 将您的Matlab类返回为struct中字段的值.

1. Define your variable as global , and access it with several functions that wrap its methods
2. Return your Matlab class as a value of field in struct.

以下是(1)的代码段:

Here is a code snippet for (1):

function CreateMyClass(st)
    global myClass;
    myClass = MyClass(st);
end

function DisplayMyClass()
    global myClass;
    myClass.display();
end
