Abstract EN
The paper aims at establishing a fast numerical algorithm for B k ( f ) , where f is any function in the Hardy space H 2 ( T d ) and k is the scale level.
Here, B k ( f ) is an approximation to f we recently constructed by applying the multiscale transform to the Cauchy kernel.
We establish the matrix expression of B k ( f ) and find that it has the structure of a multilevel Hankel matrix.
Based on the structure, a fast numerical algorithm is established to compute B k ( f ) .
The computational complexity is given.
A numerical experiment is carried out to check the efficiency of our algorithm.
