Description Usage Arguments Value

View source: R/geostat3D.R

Description

Builds a matrix that can be used to rotate and/or strech a set of coordinates in order to model anisotropy.

Usage

1
2
anisotropy3D(maxrange, midrange = maxrange, minrange = midrange,
  azimuth = 0, dip = 0, rake = 0, radians = F)

Arguments

maxrange, midrange, minrange

The three semi-axes of the anisotropy ellipsoid.

azimuth, dip, rake

Orientation of the ellipsoid in geological coordinates.

radians

Are the angles in radians or degrees?

Value

A 3x3 matrix. Multiplication of a matrix of coordinates by this matrix yields the transformed coordinates. Multiplication by its inverse reverses the effect.
