coordinates2 function

Coordinate Transformations

Converts vector between Cartesian and spherical coordinate systems

cartesian_to_spherical(n)

spherical_to_cartesian(p)

spherical_to_geographical(p)

Arguments

• n: Cartesian coordinates (x, y, z) as three-column vector
• p: Spherical coordinates (colatitude, azimuth) as two-column vector

Returns

Functions return a (2- or 3-dimensional) vector representing a point in the requested coordinate system.

Examples

n <- c(1, -2, 3)
cartesian_to_spherical(n)
p <- c(50, 10)
spherical_to_cartesian(p)
