void mfem::DenseTensor::NewMemoryAndSize	(	const Memory< real_t > &	mem,
		int	i,

inline

Reset the DenseTensor to use the given external Memory mem and dimensions i, j, and k.

If own_mem is false, the DenseTensor will not own any of the pointers of mem.

Note that when own_mem is true, the mem object can be destroyed immediately by the caller but mem.Delete() should NOT be called since the DenseTensor object takes ownership of all pointers owned by mem.
