 # GaMA
-The Gravitational and Mesh Adaptation library is a set of optimized matlab classes used to model the gravitational fields of asteroids and comets. Implemented gravity models include: the spherical harmonic model [[1]](https://ntrs.nasa.gov/citations/19940025085), analytic polyhedral model [[2]](https://doi.org/10.1007/BF00053511), mascon model[[3]](https://doi.org/10.1007/s10569-022-10115-2), approximate polyhedral model [[4]](https://doi.org/10.1093/mnras/stz3461), and a curvilinear surface model [[5]](https://doi.org/10.2514/1.G006769).  It contains a number of supporting classes and functions required to initialize the gravitational models, integrate trajectories, and post-process results. The gravitational models are easy to initialize and contain methods to calculate the potential, acceleration, laplacian, and gravitational gradient given a position. It also gives the user the ability to create composite models -- superimposing as many base models as desired. The current version is serial.

 ### Getting Started
 To access the classes and functions of GaMA, add the directory tree to the run path. This can be done by running the following command:
