Description

Extract ids coordinates from a single shape or a Coo object.

Usage

coo_extract(coo, ids)

Arguments

coo

either a matrix of (x; y) coordinates or a Coo object.

ids

integer, the ids of points to sample.

Value

a matrix of (x; y) coordinates, or a Coo object.

Details

It probably only make sense for Coo objects with the same number of coordinates and them being homologous, typically on Ldk.
