edge_quality()

C_FUNC_DEF void edge_quality	(	int	num_nodes,
		double	coordinates[][3],
		unsigned int	metrics_request_flag,
		struct EdgeMetricVals *	metric_vals
	)

higher order function for calculating multiple metrics at once.

for an edge, there is only one metric, edge length.

v_edge_length()

C_FUNC_DEF double v_edge_length	(	int	num_nodes,
		double	coordinates[][3]
	)

Calculates edge length.

length of and edge length is calculated by taking the distance between the end nodes
