Inversion |
|
dinver |
0.5.6 |
Graphical environment to solve inversion problem using Neighborhood Algorithm or Monte-Carlo sampling. Various plugins are proposed here for solving common problems. You can define your own based on the template provided here below. |
|
dinverdc |
1.4.1 |
Inversion of dispersion curves (Rayleigh, Love, Phase and Group velocities, higher modes), autocorrelation curves, ellipticity curves, ellipticity peak and refraction travel times. Joint inversion are also possible. |
|
dinverext |
0.2.1 |
Plugin to run the forward computation in an external command. |
|
dinvermatlab |
0.1.1 |
Plugin to run the forward computation in Matlab. |
|
swim |
0.1.0 |
A graphical environment for the inversion of dispersion curves. Compared to dinver, the parameterization is fully automatic, scanning across all possible numbers of layers (2 to N). Just input a dispersion curve, you will get a collection of good models without making any difficult choice about the parameterization. Though this tool might look as a black box and much easier to use, a good knowledge of the inversion process is ABSOLUTELY required (under development). |
