◆ getDistFromLTM()

RDKIT_SIMDIVPICKERS_EXPORT double RDPickers::getDistFromLTM	(	const double *	distMat,
		unsigned int	i,
		unsigned int	j )

function to lookup distance from 1D lower triangular distance matrix

Parameters

distMat	- a pointer to a 1D lower triangular distance matrix
i	- row index
j	- column index RETURNS:

if (i == j) : 0.0 if (i > j) : distMat[i*(i-1)/2 + j] if (j < i) : distMat[j*(j-1)/2 + i]
