On the MATLAB Apps tab, on the far right of the Apps section, click the arrow. In Application Deployment, click Library Compiler.

Alternatively, you can open the Library Compiler app from the MATLAB command prompt.

libraryCompiler

In the Type section of the toolstrip, click .NET Assembly.

In the Library Compiler app project window, specify the files of the MATLAB application that you want to deploy.

The function is added to the list of exported function files. Repeat this step to package multiple files in the same application.

For this example, select the file makesquare.m.

In the Packaging Options section of the toolstrip, decide whether to include the MATLAB Runtime installer in the generated application by selecting one of the options:

If you have not already created the file makesquare.m, copy the example file located in matlabroot\toolbox\dotnetbuilder\Examples\VS15\NET\MagicSquareExample\MagicSquareComp.

copyfile(fullfile(matlabroot,'toolbox','dotnetbuilder','Examples',...
'VS15','NET','MagicSquareExample','MagicSquareComp','makesquare.m'));

Save the following code in a sample file named makesquareSample1.m:

x = 5;
y = makesquare(x);

Build the .NET assembly using the compiler.build.dotNETAssembly function. Use name-value arguments to specify the assembly name, class name, and sample file.

buildResults = compiler.build.dotNETAssembly(appFile,...
'AssemblyName','MagicSquareComp',...
'ClassName','MagicSquareClass',...
'SampleGenerationFiles','makesquareSample1.m');

You can specify additional options in the compiler.build command by using name-value arguments. For details, see compiler.build.dotNETAssembly.

The compiler.build.Results object buildResults contains information on the build type, generated files, included support packages, and build options.

The function generates the following files within a folder named MagicSquareCompdotNETAssembly in your current working directory:

Open Microsoft Visual Studio and create a C# Console App (.NET Framework) called MainApp.

Remove any source code files that were created within your project, if necessary.

Add the sample C# application code makesquareSample1.cs that was generated in the samples folder to the project.

The program listing is shown below.

/// <summary>

class makesquareSample1 {

        Object[] results = null;
        try {
            MWNumericArray xIn = new MWNumericArray(xInData);
            results = MagicSquareClassInstance.makesquare(1, xIn);
            if (results[0] is MWNumericArray) {
                yOut = (MWNumericArray) results[0];
            }
            Console.WriteLine(yOut);
        } catch (Exception e) {
            Console.WriteLine(e);
        }
    }

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    static void Main(string[] args) {
        try {
            Setup();
        } catch (Exception e) {
            Console.WriteLine(e);
            Environment.Exit(1);
        }
        try {
            makesquareSample();
        } catch (Exception e) {
            Console.WriteLine(e);
            Environment.Exit(1);
        }
    }
}

The program does the following:

In Visual Studio, add a reference to your assembly file MagicSquareComp.dll located in the folder where you generated or installed the assembly.

Add a reference to the MWArray API.

Go to Build, then Configuration Manager, and change the platform from Any CPU to x64.

After you finish adding your code and references, build the application with Visual Studio.

The build process generates an executable named makesquareSample1.exe.

Run the application from Visual Studio, in a command window, or by double-clicking the generated executable.

The application returns the same output as the sample MATLAB code.
