Sparse Linear Algebra and Geophysical Migration
The pre-stack depth migration of reflection seismic data can be expressed, with the framework of waveform inversion, as a linear least squares problem. While defining... -
An Augmented Subspace Conjugate Gradient
Many scientific applications require to solve successively linear systems Ax=b with different right-hand sides b and a symmetric positive definite matrix A. The... -
