Downloading & Dependencies

The code can be found in the SLIM sofware release under /applications/WaveformInversion/3DBatching.

The code has been tested with Matlab R2012b and requires the Parallel Computing Toolbox for some of the functionality.

This code uses the following packages, also found in the tools part of the SLIM software release.

Running & Parallelism

All the examples and results are produced by the scripts found in this software release under applications/WaveformInversion/3DBatching/. Start matlab from that directory or run startup in that directory to add the appropriate paths.

To run the scripts follow the instrictions in the README file enclosed with the code. Most scripts can be run in serial mode.

Functions

The functions specific to this package can be found in the mbin directory.

Examples and results

Scripts to reproduce some of the examples found in [3] can be found in the scripts directory. The results are shown here.
