prod() [4/6]

template<Rank summed, Rank frank, Rank srank>

std::enable_if_t<frank + srank - 2 * summed != 0, Tensor<frank + srank - 2 * summed> > syten::prod ( Tensor< frank > const &  a, Tensor< srank > const &  b, std::string_view  prodspec, Conj const  conj = Conj::n(), EliminateZeros const  ezeros = EliminateZeros::No, SourceLocation  location = SourceLocation::current()  )

Preferred form of the Tensor-Tensor-to-Tensor product.

Parameters

a	first tensor
b	second tensor
prodspec	Einstein summation specification, e.g. a,b,c|c,d,e|a,e,d,b
conj	if Yes, complex-conjugate the second tensor
ezeros	if EliminateZeroes::Yes, eliminate zeroes.
location	Callsite identifier.
