Integrate SimpleMATLABFunction Into .NET Application

Note

The examples for theMATLAB^®Compiler SDK™product are inMatlabroot\toolbox\dotnetbuilder\Examples\VS版本, wherevs版本指定版本Microsoft^®视觉工作室^®.NET您正在使用。您可以通过在Visual Studio中打开以下解决方案来为所有示例加载项目：

Matlabroot\toolbox\dotnetbuilder\Examples\VS版本\ dotnetexamples.sln

The简单的情节example shows you how to create a .NET assembly that calls a MATLAB function to display a plot. For an example that uses a MATLAB function to modify a structure array, seePhone Book.

在以下示例中，您执行以下步骤将MATLAB函数集成到.NET应用程序中：

Use theMATLAB编译器SDKproduct to convert a MATLAB function to a method of a .NET class and wrap the class in a .NET assembly.
访问C＃应用程序或Visual Basic中的组件^®通过实例化.NET类并使用MWArray班级库处理数据转换。
Build and run the generated application using the Visual Studio .NET development environment.

Prerequisites

Verify that you have met all of theMATLAB编译器SDK.NET target requirements. For details, seeMATLAB编译器SDK .NET目标要求.
Verify that you haveMicrosoft Visual Studioinstalled.
End users must have an installation ofMATLAB Runtime运行应用程序。有关详细信息，请参阅Install and Configure MATLAB Runtime.
For testing purposes, you can use an installation of MATLAB instead ofMATLAB Runtime.

程序

Copy the following folder that ships with the MATLAB product to your work folder:
```
Matlabroot\toolbox\dotnetbuilder\Examples\VS版本\NET\PlotExample
```
在MATLAB命令提示下，导航到PlotExample\PlotCompsubfolder in your work folder.
Examine thedrawgraphfunction located inPlotExample\PlotComp.
```
functiondrawgraph(coords) plot(coords(1,:), coords(2,:)); pause(5)
```
测试函数在MATLAB命令提示符。
```
x = 0:0.01:10; y = sin(x); z = [x;y]; drawgraph(z)
```
The function outputs a figure that displays a sine wave.

Build the .NET component with theLibrary Compilerapp orcompiler.build.dotNETAssemblyusing the following information:

场地	价值
Library Name	`PlotComp`
Class Name	`Plotter`
File to Compile	`drawgraph.m`

For example, if you are usingcompiler.build.dotNETAssembly, type:

buildResults = compiler.build.dotnetassembly（'drawgraph.m',...'AssemblyName','PlotComp',...'班级名称','Plotter');

For more details, see the instructions in生成.NET组件并构建.NET应用程序.

确定您是使用C＃还是Visual Basic来访问组件。

If you are using C#, write source code for a C# application that accesses the component.

此示例的示例申请在PlotExample\PlotCSApp\PlotApp.cs.

PlotApp.cs

This statement creates an instance of thePlotter班级：

绘图器绘图器= new Ploter（）;

This statement explicitly casts the native阴谋价值stomwnumericarrayand then calls the methoddrawgraph:

plotter.drawgraph（（（mwnumericArray）plotValues）;

视觉基本

If you are using Visual Basic, write source code for a Visual Basic application that accesses the component.

此示例的示例申请在PlotExample\PlotVBApp\PlotApp.vb.

plotapp.vb

This statement creates an instance of thePlotter班级：

DIM绘图仪为绘图器=新绘图仪

此语句调用方法drawgraph:

阴谋ter.drawgraph(coords)

无论哪种情况，PlotApp程序执行以下操作：

Creates two arrays of double values.
Creates aPlotter目的。
Calls thedrawgraph使用MATLAB绘制方程的方法阴谋功能。
用途mwnumericarray表示由drawgraphmethod to plot the equation.
使用试着抓block to catch and handle any exceptions.
