Hi Johannes,
In article <87iph4$3vb at smc.vnet.net>, "Johannes Ludsteck"

If you set arguments in the template like {y,x,kernelWidth}, you
must read each of them according to the order and type, because
these are put on the link.
So, I suppose your MLGetRealArray does not read the correct data.
Before reading x by MLGetArray, you must read y using MLGetRealList
or MLGetIntegerList.
void kerndens(void)
{
double **x, temp;
long *dimsx, depthx;
char **headsx;
MLGetRealArray(stdlink, &x, &dimsx, &headsx, &depthx);
MLPutReal(stdlink, x[0][0]);
MLDisownRealArray(stdlink, x, dimsx, headsx, depthx);
}
The template file has the following form:
:Begin:
:Function: kerndens
:Pattern: kerndens[y_List,x_?MatrixQ,kernelWidth_Real]
:Arguments: {y,x,kernelWidth}
:ArgumentTypes: {Manual}
:ReturnType: Manual
:End:
