[Visual Basic .NET]
Public Function PrincipalComponents ( _
    ByVal rasterBands As IGeoDataset, _
    ByVal dataFile As String, _
    [ByVal numberComponents As Object] _
) As IGeoDataset

[C#]
public IGeoDataset PrincipalComponents (
    IGeoDataset rasterBands,
    string dataFile,
    object numberComponents
);

[C++]
HRESULT PrincipalComponents(
  IGeoDataset* rasterBands,
  BSTR dataFile,
  VARIANT numberComponents,
  IGeoDataset** pcaDataset
);

[C++]

Parameters
rasterBands [in]

  rasterBands is a parameter of type IGeoDataset
dataFile [in]
  dataFile is a parameter of type BSTR
numberComponents [optional]
  numberComponents is a parameter of type VARIANT
