## Contents

## Downloading & Dependencies

The code can be found in the SLIM sofware release under `/applications/WaveformInversion/2DWRI-SourceEstimation/`.

The code has been tested with *Matlab R2015b* and requires the Parallel Computing Toolbox.

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

*utilities/SPOT*- object oriented framework for matrix-free linear algebra.*utilities/pSPOT*- parallel extension of SPOT.*operators/misc*- Misc. operators such as interpolation, smoothing and splines*functions/misc*- Misc. functions.*tools/solvers/QuasiNewton/minConf_mod/*- nonlinear optimization

## Running & Parallelism

All the examples and results are produced by the scripts found in this software release under `/applications/WaveformInversion/2DWRI-SourceEstimation/`. 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.
