PyGrav is a toy for playing with the 2D gravity problem. It allows you to change a density model in the directions of the singular vectors of the sensitivity matrix, and view the effect on the data. Recently added 3D modeling capability.
Get the code:
git clone https://github.com/AndyMcAliley/pygrav.git
Run the code:
python toy.py
Use it for gravity modeling: copy grav.py to your project
import grav
G = grav.sens3d(x_nodes,y_nodes,z_nodes,observation_locations)For more details, see the grav_example.ipynb notebook.
