vrrotvec

Calculate rotation between two vectors

Syntax

r = vrrotvec(a,b)

r = vrrotvec(a,b,options)

Description

r = vrrotvec(a,b) calculates a rotation needed to transform the 3D vector a to the

3D vector b.

r = vrrotvec(a,b,options) calculates the rotation with the default algorithm

parameters replaced by values defined in options.

The options structure contains the parameter epsilon that represents the value below

which a number will be treated as zero (default value is 1e-12).

The result, r, is a four-element axis-angle rotation row vector. The first three elements

specify the rotation axis, and the last element defines the angle of rotation.
