coo_smoothcurve: Smoothes coordinates on curves

Description

Smoothes coordinates using a simple moving average but let the first and last points unchanged. May be useful to remove digitization noise on curves.

Usage

coo_smoothcurve(coo, n)

Arguments

coo

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

n

integer to specify the number of smoothing iterations

Value

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