- pwtools.num.inner_points_mask(points)[source]¶
Mask array into points where
points[msk]
are all “inner” points, i.e. points with one level of edge points removed. For 1D, this is simply points[1:-1,:] (assuming ordered points). For ND, we calculate and remove the convex hull.- Parameters:
points (nd array (npoints, ndim))
- Returns:
msk – Bool array.
- Return type:
