bh_tomo is an open source borehole georadar/seismic data processing and
ray-based 2D and 3D tomography software package.
## Installation
Copy the files in the bh_tomo directory somewhere in your MATLABPATH or add
the bh_tomo directory to your MATLABPATH.
### Compatibility
This version requires Matlab 2015b and onward.
### MEX files
You might need to compile mex files if not already available for
your platform. To do so, follow the steps:
```
cd /path/to/bh_tomo/mex_src ( where the source code is )
mex -O -largeArrayDims Lsr2d.c
mex -O -largeArrayDims Lsr3d.c
mex -O -largeArrayDims Lsr2da.c
mex -O -largeArrayDims grid2d_mex.cpp
mex -O -largeArrayDims grid3d_mex.cpp
mex -O -largeArrayDims read_segy_b_header.c
mex -O -largeArrayDims read_segy_tr_headers.c
mex -O -largeArrayDims read_segy_data.c
mv *.mex* ../bh_tomo % (to put the mex files in the main directory of bh_tomo)
```
Invocation of the command mex can be performed in matlab, at the
command prompt.
**Important**: you need a compiler that supports the C++11 standard to
compile most of the mex functions. This has to be enabled in your
mex setup.
