class Fourier {
	public:
		...

		Fourier( int K_, double* Xtrain_, int XTrainLength_, double* Xtest_, int XTestLength_, double* L_, double* centers_, int centersLength_, double* alphas_, double sigma_ );
...
};

...

Fourier::Fourier( int K_, double* Xtrain_, int XTrainLength_, double* Xtest_, int XTestLength_, double* L_, double* centers_, int centersLength_, double* alphas_, double sigma_ ) {
...
}

Und so erzeuge ich ein Objekt:

Fourier fourier( K, Xtrain, XtrainLength, Xtest, XtestLength, L, centers, centersLength, alphas, sigma );

Wenn ich es kompiliere erhalte ich folgende Fehlermeldung:

make
g++ -fPIC -ansi -DMX_COMPAT_32 -DMATLAB_MEX_FILE -I/Applications/MATLAB_R2009b.app/extern/include -c FourierDifference7D.cpp

Was mache ich falsch?

void mexFunction( int nlhs, mxArray* plhs[], int nrhs, const mxArray* prhs[] ) {

	if( nrhs < 7 )
		mexErrMsgTxt("[f,g] = FourierDifference7D( Xtrain, Xtest, centers, L, sigma, alpha, K )\n");

	const mwSize* dimsCount1 = mxGetDimensions(prhs[0]);
	if( dimsCount1[1] != 7 || (dimsCount1[0] < dimsCount1[1]))
		mexErrMsgTxt("First argument (Xtrain) must be a Nx7 data matrix.\n");
	double *Xtrain = mxGetPr(prhs[0]);
	int XtrainLength = dimsCount1[0];

	double *Xtest = mxGetPr(prhs[1]);
	int XtestLength = dimsCount2[0];

	double *centers = mxGetPr(prhs[2]);
	int centersLength = dimsCount3[1];

	const mwSize* dimsCount4 = mxGetDimensions(prhs[3]);
	if( dimsCount4[0] != 1 || dimsCount4[1] != 7 )
		mexErrMsgTxt("Fourth argument (L) must be a 1x7 vector of period lengths.\n");

		mexErrMsgTxt("Fifth argument (sigma) must be a scalar.\n");
	double sigma = *(mxGetPr(prhs[4]));

	const mwSize* dimsCount6 = mxGetDimensions(prhs[5]);
	if( !( dimsCount6[0] == centersLength || dimsCount6[1] == centersLength ) )	
		mexErrMsgTxt("Sixth argument (alpha) must be the same length as centers.\n");
	double *alphas = mxGetPr(prhs[5]);

	const mwSize* dimsCount7 = mxGetDimensions(prhs[6]);

	int K = (int) *(mxGetPr(prhs[6]));

	if( nlhs < 1  )
		mexErrMsgTxt("Return value is missing.\n[f,g] = FourierDifference7D( Xtrain, Xtest, centers, L, sigma, alpha, K )\n");

	plhs[0] = mxCreateDoubleScalar(0.0);
	double* f = mxGetPr(plhs[0]);

	Fourier fourier( K, Xtrain, XtrainLength, Xtest, XtestLength, L, centers, centersLength, alphas, sigma );
        ...

Die Methde mxGetPr(prhs[6]) liefert immer einen Pointer vom Typ Double zurück (http://www.mathworks.com/help/techdoc/apiref/mxgetpr.html)

double L = *mxGetPr(prhs[3]);

geschrieben es muss aber

double* L = mxGetPr(prhs[3]);

lauten.

Vielen Dank für Eure Hilfe.
