【正文】 ferent time and place for the development of the code can be coordinated to operate as well as the sharing of binary code. In the COM world, the application of software ponents built by different. These ponents in strict pliance with the provisions of the rules of COM, even if the language is different from the development of time, place different, but they can be perfectly patible, the application of their software to plete certain functions. For these ponents, the function of the expansion or the increase of new features will not damage the function of the original. COM mentioned in the binary code, generally known as COM or COM object. COM object is different from the C + + language in the object. C + + object is a practical problem for the abstract, is a means of software development. The COM provides a binary code can be shared industry standard. COM ponent is the core technology of the Windows operating system. Theoretically, COM can be crossplatform. But almost all current applications are in the COM under Windows operating system. In general, COM objects can be in two formats: one is the form of COM DLL, in the actual call, the ponent code was included in the process of applications, so that COM ponents are also referred to as the process of inside (inproc) ponents. Another ponent is a Windows executable file (. Exe files). Such ponents in practical applications can run on its own independent process, so called process ponents (outofproc) ponents. MATLAB Compiler generated DLL files are COM objects, that is, the process ponents. COM theory does not rely on a particular programming language. This means that the development of COM ponents, COM ponents and the use of application software are not just limited to a particular programming language. Speaking from a technical difficulty, the use of COM to develop their formation than the more simple. Building COM Objects You can use mbuild to create Component Object Model (COM) objects from MATLAB Mfiles. The collection of Mfiles is translated into a single COM class. MATLAB COM Builder supports multiple classes per ponent. The interface to the COM class is the same set of functions that are exported from a C shared library, but the Compiler supports both C and C++ code generation in producing COM objects. mbuild automatically: ?Invokes the Microsoft Interface Definition Language (MIDL) piler ?Invokes the resource piler ?Specifies the .DEF files Using mbuild options you can enable auto registration of the COMpatible DLL. For example, to pile into a COM object, use mcc B 39。添加工具箱 (專用 MATLAB 的匯集分開地起作用，可利用 )在這些應用范圍擴大 MATLAB 環(huán)境解決問題特殊類。交互式的編程環(huán)境，內(nèi)置的數(shù)學運算功能，工具箱，編輯和調(diào)試工具，和部署選項都有助于降低您的整體開發(fā)。您能集成您的 MATLAB代碼以其他語言和應用，并且分布您的 MATLAB 算法和應用。 文獻翻譯 ： 導言 介紹 MATLAB 是一個高級技術(shù)計算的語言和交互式環(huán)境為算法發(fā)展、數(shù)據(jù)形象化、數(shù)據(jù)分析和數(shù)字計算，使用 MATLAB，您能快速地解決技術(shù)計算的問題比以傳統(tǒng)編程語言，例如 C， C++和 FORTRAN。re ready to deploy your application, the MathWorks offers a number of different options that allow you to either convert or interface your MATLAB application to other environments including C/C++ and the Web. MATLAB is the most productive development environment for creating scientific and engineering applications because it offers powerful tools for every step in the process to reduce your overall development time. Use MATLAB is a highperformance language for technical puting. It integrates putation, visualization, and programming in an easytouse environment where problems and solutions are expressed in familiar mathematical notation. Typical uses include ? Math and putation ? Algorithm development ? Data acquisition ? Modeling, simulation, and prototyping ? Data analysis, exploration, and visualization ? Scientific and engineering graphics ? Application development, including graphical user interface building Compiled files Type The MATLAB Compiler takes Mfiles as input and generates C or C++ source code or Pcode as output. The MATLAB Compiler can generate these kinds of source code: ?C source code for building MEXfiles. ?C or C++ source code for bining with other modules to form standalone applications. Standalone applications do not require MATLAB at runtime。 在整個設計過程中，我得到了馬中武老師的悉心指導和幫助。在這次設計過程中，我明顯感覺到自己在許多方面存在不足，譬如，對Word 的熟練使用，對 MATLAB 軟件的應用，對 PID 控制器的認識，電烤爐的了解等等。在這次畢業(yè)設計中，我的任務是完成 PID 溫控系統(tǒng)的設計（ MATLAB）。中國科技研究院電工研究所 ,2020.
