MATdrr

Description

MATdrr is a Matlab package for the damped rank reduction (DRR) method and its several variants. The DRR method has a variety of applications in both exploration and earthquake seismology, including but not limited to seismic denoising, seismic reconstruction, seismic diffraction separation, constrained LSRTM, constrained FWI, etc. Since Feb, 22, 2023, this official site of MATdrr package has been moved to https://github.com/aaspip/MATdrr. The current site of the package is no longer maintained.

The Python counterpart of the package can be found at https://github.com/aaspip/pydrr.
