我試圖將MATLAB 2010b與Visual Studio 2008 Professional集成。MATLAB .NET程序集（未定義函數或變量'feedforwardnet'）
我有以下的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
這是我如何創建我的DLL文件在Visual Studio中導入：
%%// 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 '''']);
所以當我用MATLAB Engine'sCOM接口從C＃內運行MATLAB日常的一切工作完全正常：
/*
* 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，當我使用.NET程序集，它不承認'feedforwardnet'。我曾經在第86行（net(data_inputNN)）上遇到錯誤。所以我添加了一行來測試它是否至少能識別'feedforwardnet'，但它沒有。
注：我加載從一個文件中的一些變量，包括「網」，這是一個神經網絡（load(args.workspacePath, '-regexp', '.*');）
此外，在如果我從文件加載保存的「網絡」，然後將其保存在MATLAB方法看看它如何處理網絡，它會將其保存爲「結構」而不是「網絡」。
我假設它將它加載爲一個結構開始。
我在MATLAB 2009b本身內部也有這個問題。這就是我現在使用MATLAB 2010b的原因，因爲顯然，MATLAB 2009b沒有這個特定的神經網絡工具箱。
以下是使用.NET程序集的C＃代碼。
/*
* 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;
}
}
我得到這個錯誤在Visual Studio：
... MWMCR::EvaluateFunction error ...
Undefined function or variable 'feedforwardnet'.
Error in => perform.m at line 81.
注：版本我的編譯器和軟件的：
編譯器：微軟的Visual C++ 2008 SP1中C:\Program Files (x86)\Microsoft Visual Studio 9.0
MATLAB：R2010b（64位）
的Visual Studio：MVS 2008專業（的.NET Framework 3.5 SP1）
的Microsoft Windows SDK 6.1
最近更新：
我已經添加了神經網絡的路徑工具箱mcc。
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 '''']);
現在我在mccExcludeFiles.log得到這些信息：
C：\ Program Files文件\ MATLAB \ R2010b中的\工具箱\ NNET \ NNET \ @network \網絡。米
用C稱爲：\ Program Files文件\ MATLAB \ R2010b中的\工具箱\ NNET \ NNET \ nnnetwork \ cascadeforwardnet.m（因爲工具箱compilability規則）
C：\ Program Files文件\ MATLAB \ R2010b中\工具箱\ NNET \ NNET \ @network \ network.m
