Selecting the optimal Parameters Results in Double Interpolation: Double AFD

Tao Qian, Yunni Wu, Wei Qu +1

Let $f$ belong to the Hardy space $H^{2} (D)$ of the unit disc, and $e_{a}$ the normalized SzegÃ¶ (reproducing) kernel of $H^{2} (D) .$ It is well known that, due to the r…

Matrix Pre-orthogonal Matching Pursuit and Pseudo-Inverse

Wei Qu, Chi Tin Hon, Yiqiao Zhang +1

We introduce a new fundamental algorithm called Matrix-POAFD to solve the matrix least square problem. The method is based on the matching pursuit principle. The method directly ex…
