interp_error_nd

sofia_redux.toolkit.interpolate.interpolate.interp_error_nd(points, error, xi, cval=nan)

Propagate errors using Delaunay triangulation in N-dimensions

Uses interp_error_1d to propagate errors in 1-dimension following linear interpolation, or propagates errors in N-dimensions when Delaunay triangulation has been used for linear interpolation.

This is not accurate for any other type of interpolation other than the types mentioned above.

Parameters:

pointsnumpy.ndarray (nsamples, ndim) or Delaunay triangulation

Coordinates of points or the pre-computed scipy.spatial.Delaunay triangulation.

errorfloat or numpy.ndarray (nsamples,)

Error at each point.

xinumpy.ndarray (npoints, ndim)

Points at which to interpolate data.

cvalfloat, optional

Value to fill in requested interpolation points outside the data range.

Returns:

numpy.ndarray (npoints,)
