Detailed Description

Boris Jeremic tensor class.

Constructor & Destructor Documentation

BJtensor()

XC::BJtensor::BJtensor	(	int	rank_of_BJtensor = 1,

This is supposed to fill in the string indices1 or the string indices2 strings in BJtensor object so that they can be checked for matching later on when operations like single contraction (.), double contraction (:), dyadic product (otimes) are performed the object can choose the right operator.

Also when multiplying XC::BJtensor by itself ( like for example: D("ij")*D("kl") the other string indices2 is defined to take the other array of indices so that mulitplication will be O.K. Since only two BJtensors can be multiplied at the time ( binary operation ) only indices1 and indices2 are needed.
