AdaptiveStieltjesAlgorithm¶
- class AdaptiveStieltjesAlgorithm(*args)¶
AdaptiveStieltjes algorithm used to build the orthonormal basis.
The algorithm builds a polynomial basis orthonormal with respect to a specific distribution.
- Parameters:
- measure
Distribution
A measure for which the orthonormal polynomial basis is built.
- measure

Notes
It implements an adaptive Stieltjes algorithm that builds the polynomial family orthonormal with respect to the distribution measure, using the
GaussKronrod
adaptive integration method to compute the following dot-products: and where is the monic polynomial associated to the orthonormal polynomial , needed to compute the coefficients of the three-terms recurrence relation that defines (seeOrthogonalUniVariatePolynomialFamily
):where , , and .
