Hansen (scientific computing, Technical U. of Denmark) offers an overview of computational stabilization methods for linear inversion, with applications to a variety of problems in audio processing, medical imaging, tomography, seismology, astronomy, and other areas. He addresses applied mathematicians who are familiar with the underlying theory of inverse problems and have some background in numerical linear algebra and matrix computations. His public-domain MATLAB software package Regularization Tools is available to complement the book. Annotation c. by Book News, Inc., Portland, Or.
