发帖数: 13 | 3 if your solution/matrix do not have sparsity, there is no meaning to use
wavelet approach for numerically solve PDE.
Advantages for Wavelet approach:
1. Wavelet method combine(O(N)) the advantages of both spectral (O(N Log_2 N
)) and finite difference methods
and allow both space and time dependent coefficients;
2. Large classes of operators and functions are sparse or sparse to high
accuracy when transformed into the wavelet domain;
3. It is suitable for problems with the multiple spatial |

By SARA ROBINSON
Russian mathematician is reporting that he has proved the Poincaré
Conjecture, one of the most famous unsolved problems in mathematics.
The mathematician, Dr. Grigori Perelman of the Steklov Institute of
Mathematics of the Russian Academy of Sciences in St. Petersburg, is
describing his work in a series of papers, not yet completed.
It will be months before the proof can be thoroughly checked. But if true, it
