Smoothes coordinates using a simple moving average but let the first and last points unchanged. May be useful to remove digitization noise on curves.
Arguments
- coo
matrixof(x; y)coordinates or any Coo object.- n
integerto specify the number of smoothing iterations
Value
a matrix of (x; y) coordinates, or a Coo object.
