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.
