avectors: Computes the angle between two vectors

In aaronolsen/StereoMorph: Stereo Camera Calibration and Reconstruction

Computes the angle between two vectors

Description

This function returns the angle (in radians) between two vectors. The vectors can be of any dimension.

Usage

avectors(u, v)

Arguments

u	a vector
v	a vector

Value

the angle (in radians) between the two input vectors.

Examples

## THE ANGLE BETWEEN TWO 2D, ORTHOGONAL VECTORS
## VALUE IS EQUAL TO asin(1/sqrt(2))
u <- c(0, 1)
v <- c(1, 0)
avectors(u, v)

## THE ANGLE BETWEEN TWO 3D VECTORS
## VALUE IS EQUAL TO asin(sqrt(2)/sqrt(3))
u <- c(1, 1, 1)
v <- c(0, 1, 0)
avectors(u, v)
