Detailed Description

An interface class for an N-dimensional tensor of numeric objects, and engines class for defining a general tensor, using Full and Antisymmetric engine tag classes.

template<class T >

void reverseBytes

T &

t

)

[inline]

The exported interface to the above template is the global reverseBytes template.

The general template delegates directly to the ByteReverser class above.

template<int D, class T , class E >

std::ostream& operator<<	(	std::ostream &	out,
		const Tensor< D, T, E > &	t
	)

Output to a stream.

The format is: ( ( t(0,0) t(0,1),... ) ( t(1,0) t(1,1) ... ) ... )

The actual symmetrize() global function template.

To get around problems with partially specializating on return type, introduce the Symmetrize functor class, which the symmetrize() function uses. The partial specializations are of the Symmetrize functor. Forward declare the functor before the function template:
