Gravitational and magnetic attraction of 3-D vertical rectangular prisms

Description

The package gravmagsubs provides tools for computing the gravitational and magnetic anomalies generated by 3-D vertical rectangular prisms at specific observation points. The package consists of two functions:

  • rectprismgrav : Computes the gravitational attraction of 3-D right rectangular prisms.

  • rectprismmag : Computes the magnetic effect of 3-D right rectangular prisms.

Each function can compute the total anomaly of a series of N prisms at M observation points.

Each function also has a logical flag bycell (default FALSE). If bycell=TRUE, the function returns the contribution from each individual prism.
