# PairSDevDistance

Computes the standard deviation of edge pair distances.

## PairSDevDistance Inputs

Parameter | Description
Edges | A reference to a spreadsheet cell containing an Edge data structure, which must consist of multiple straight-line edges. The function expects the input Edge data structure to be sorted by pairs, such that evenly-indexed edges contain the first edge of an edge pair, and oddly-indexed edges contain the second edge of an edge pair.

## PairSDevDistance Outputs

Returns | A value representing the standard deviation of edge pair distances, or #ERR if any of the input parameters are invalid.
