Definition at line 27 of file SGMatrix.hxx.
Default constructor.
Does not initialize at all. If you need them zero initialized, use SGMatrix::zeros()
Initialize with nans in the debug build, that will guarantee to have a fast uninitialized default constructor in the release but shows up uninitialized values in the debug build very fast ...
Definition at line 34 of file SGMatrix.hxx.
Constructor.
Initialize by the content of a plain array, make sure it has at least 16 elements
