GitHub - emadghalenoei/Matrix_Wavelet_Compression: This python code takes a huge matrix (e.g. 3D gravity kernel) as an input and then performs wavelet compression to improve the efficiency of matrix multiplication. Note that the multiplication of two matrices in the wavelet domain is equal to the multiplication in the real domain. This wavelet compression was introduced by Li and Oldenburg, 2003 Fast inversion of large-scale magnetic data using wavelet transforms and a logarithmic barrier method.
