MATLAB .NET 汇编(未定义的函数或变量“feedforwardnet”)

我正在尝试将 MATLAB 2010b 与 Visual Studio 2008 Professional 集成。

我有以下 MATLAB 方法。

function varargout = perform( func, varargin )
%% // Set default values
workspaceDirectory = ['Results/MatlabWorkspace_' datestr(now, 'yyyy-mm-dd_HH-MM-SS')];
clear args
args = struct('workspacePath', [ workspaceDirectory '/workspace.mat'], ...
              'testArray', [], ...
              'k', 50, ...
              'rate', 0.0001, ...
              'trainingDataPath', 'P2AT_LaserImageVectorList.csv', ...
              'network', 'feedforwardnet', ...
              'initialWeights', [], ...
              'divideFcn', 'dividerand', ...
              'trainRatio', 70/100, ...
              'testRatio', 15/100, ...
              'valRatio', 15/100, ...
              'trainInd', [], ...
              'testInd', [], ...
              'valInd', [], ...
              'trainFcn', 'trainlm', ...
              'performFcn', 'mse', ...
              'biasConnect', [0; 0; 0], ...
              'layerSize', [9; 4; 1], ...
              'layerTransferFcn', ['tansig '; 'tansig '; 'purelin'], ...
              'max_fail', 10, ...
              'mu_dec', 0.04, ...
              'useInitialWeights', false, ...
              'saveResults', true);
% // Returns a modified properties structure
args = getopt(args,varargin);
args.layerTransferFcn = cellstr(args.layerTransferFcn);
if args.saveResults && ~strcmpi(func,'test')
    if (exist(workspaceDirectory, 'dir') ~= 7)
        mkdir(workspaceDirectory);
    end
end
if (strcmpi(func,'test'))
    try
        load(args.workspacePath, '-regexp', '.*');
    catch err
        Warning(err.message);
        varargin{1,1} = null;
        return;
    end
    data_inputAngle = args.testArray(2501);
    data_inputPCA = args.testArray(1:2500);
    if size(data_inputPCA,1) == 1
        data_inputPCA = data_inputPCA';
    end
    switch(featureExtractionMethod)
        case {'gha','apex'}
            % // [W, errvals] = gha(data_inputPCA, k, varargin{1,3});
            data_PCs  = W' * data_inputPCA;
            data_inputNN = [data_PCs; data_inputAngle];
        case 'nnmf'
            % // [W,H,D] = nnmf(data_inputPCA',k);
            data_PCs  = H * data_inputPCA;
            data_inputNN = [data_PCs; data_inputAngle];
        case 'pcaProcess'
        otherwise
            warning = 'ERROR: no feature extraction method has been defined.';
            Warning('ERROR: no feature extraction method has been defined.');
            varargout{1,1} = null;
            return;
    end
    % // Just to test to see if it recognizes 'feedforwardnet'.
    testnet = feedforwardnet;    % // <------------------------------- LINE 81
    % // Saving all the workspace variables to see if they are all correctly processed.
    save('all');
    varargout{1,1} = net(data_inputNN); %// <------------------------- LINE 86
    end
end

这就是我创建要在Visual Studio中导入的DLL文件的方式：

%%// Determine path names
workdir = pwd();
outdir = fullfile(workdir, 'Output');
dnetdir = fullfile(workdir, 'dotnet');
%%// Determine file names
mfile = fullfile(workdir, 'perform.m');
dnetdll = fullfile(dnetdir, 'dotnet.dll');
%%// Build .NET Assembly
eval(['mcc -N -d ''' dnetdir ''' -W ''dotnet:dotnet,' ...
        'dotnetclass,0.0,private'' -T link:lib ''' mfile '''']);

因此，当我使用 MATLAB Engine 的 COM 接口从 C# 在 MATLAB 中运行例程时，一切正常：

/*
 * This function calls the routine inside
 * MATLAB using the MATLAB Engine's COM interface
 */
static private float MatlabTestDebug(float[] testData, Double targetAngle)
    {
        Array X = new double[testData.Length + 1];
        testData.CopyTo(X, 0);
        X.SetValue((double)targetAngle, testData.Length);
        Array zerosX = new double[X.GetLength(0)];
        MLApp.MLAppClass matlab = new MLApp.MLAppClass();
        matlab.PutFullMatrix("testArray", "base", X, zerosX);
        matlab.PutWorkspaceData("workspacePath", "base", "workspace.mat");
        // Using Engine Interface, execute the ML command
        // contained in quotes.
        matlab.Execute("cd 'c:''Users''H''Documents''Project''Source Code''MatlabFiles';");
        matlab.Execute("open perform.m");
        matlab.Execute("dbstop in perform.m");
        matlab.Execute("result = perform('test', 'workspacePath', 'workspace.mat', 'testArray', testArray);");
        matlab.Execute("com.mathworks.mlservices.MLEditorServices.closeAll");
        return (double)matlab.GetVariable("result", "base");
    }

但是当我使用 .NET 程序集时，它无法识别"feedforwardnet"。我曾经在第 86 行 （ net(data_inputNN)） 上收到错误。所以我添加了一行来测试它是否至少识别"feedforwardnet"，但它没有。

注意：我正在从文件中加载一些变量，包括"net"，这是一个神经网络（load(args.workspacePath, '-regexp', '.*'); ）

同样在 MATLAB 方法中，如果我从文件加载保存的"网络"，然后保存它以查看它如何处理网络，它会将其保存为"结构"而不是"网络"。

我假设它首先将其加载为结构。

我在 MATLAB 2009b 本身中也遇到了这个问题。这就是我现在使用 MATLAB 2010b 的原因，因为显然 MATLAB 2009b 没有这个特定的神经网络工具箱。

下面是使用 .NET 程序集的 C# 代码。

/*
 * Calls the method from inside a .NET assembly created with MATLAB
 * using Builder for .NET.
 */
private float MatlabTest(float[] testData, Double targetAngle)
    {
        if (testData != null)
        {
            dotnetclass AClass = new dotnetclass();
            Array X = new double[testData.Length + 1];
            testData.CopyTo(X, 0);
            X.SetValue((double)targetAngle, testData.Length);
            MWNumericArray XNumericArray = new MWNumericArray(X);
            MWArray[] RetVal = AClass.perform(1, "test",
                "workspacePath", "workspace.mat",
                "testArray", XNumericArray);
            Array result = ((MWNumericArray)RetVal[0]).ToVector(MWArrayComponent.Real);
            return (float)result.GetValue(0);
        }
        else
        {
            return 0f;
        }
    }

我在Visual Studio中收到此错误：

... MWMCR::EvaluateFunction error ...
Undefined function or variable 'feedforwardnet'.
Error in => perform.m at line 81.

注意：我的编译器和软件的版本：

编译器：Microsoft Visual C++ 2008 SP1 C:'Program Files (x86)'Microsoft Visual Studio 9.0

MATLAB： R2010b（64 位）

Visual Studio： MVS 2008 Professional （.NET Framework 3.5 SP1）

Microsoft Windows SDK 6.1

最近更新：

我在 mcc 中添加了神经网络工具箱的路径。

eval(['mcc -N -p ''C:'Program Files'MATLAB'R2010b'toolbox'nnet'' -d ''' dnetdir ''' -W ''dotnet:dotnet,' ...
    'dotnetclass,0.0,private'' -T link:lib -v ''' mfile '''']);

现在我收到这些消息mccExcludeFiles.log：

C：''Program Files''MATLAB''R2010b''toolbox'net'net''@network'etwork.m

由 C：''Program Files''MATLAB''R2010b''toolbox'net'net'nnetwork''cascadeforwardnet.m 调用 （由于工具箱可编译性规则）
