warp.fem.polynomial.lagrange_scales#
- warp.fem.polynomial.lagrange_scales(coords)[source]#
Return the scaling factors for Lagrange polynomials with roots at
coords.- Parameters:
coords (ndarray) – NumPy array of coordinates defining the polynomial roots.
- Returns:
A NumPy array of scaling factors for the Lagrange basis polynomials, in which the i-th element is the reciprocal of the product of differences between
coords[i]and all other coordinates.- Return type:
