operator==() [3/3]

bool syten::STensorImpl::operator==	(	STensor const &	a,
		STensor const &	b
	)

Equality comparison of two STensor objects.

Considers two STensor objects close if A·conj(B)/sqrt(|A|*|B|) is up to sqrt((size_A + size_B) * 0.5)*SYTEN_SMALL_THRESHOLD close to

1. This is equivalent to the check done by operator== for syten::Tensor objects.
