Sampling algorithms for multivariate wavelets
Yongqiang Lian, Dandan Song, Jizheng Di · 2011
In this paper, we give algorithms to calculate multivariate wavelet coefficients approximately by sampled values of functions. Then we provide two formulae respectively to calculate the outlines and details of functions. Last, as an example, we draw figures of outline and detail of a function. 2000 AMS Classification: 42A65
