Parameters :

trace : 1D ndarray

1D array to extrapolate from and append to.

a : ndarray

LP coefficients, must be ordered according to direction of extrapolation.

pred : int

Number of points to predict using LP.

append : {‘a’, ‘b’}

Location to append new points, ‘a’ for after the current data, ‘b’ for before the current data.
