%description
Several functions introduced in Aster et al.'s book on inverse theory. The
functions are often translations of MATLAB code developed by the authors
to illustrate concepts of inverse theory as applied to geophysics.
Generalized inversion, tomographic inversion algorithms (conjugate
gradients, 'ART' and 'SIRT'), non-linear least squares, first and second
order Tikhonov regularization, roughness constraints, and procedures for
estimating smoothing parameters are included.
