Euclidean transformation
It transforms the data from the spherical coordinates to Euclidean coordinates.
euclid(u)
u |
A two column matrix or even one single vector, where the first column (or element) is the latitude and the second is the longitude. The order is important. |
It takes the matrix of unit vectors of latitude and longitude and transforms it to unit vectors.
A three column matrix:
U |
The Euclidean coordinates of the latitude and longitude. |
