Calculate rotation between two vectors


    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.

    Input Arguments

    collapse all

    3-D vectors between which rotation is being calculated.

    Data Types: single | double

    Structure containing the parameter epsilon that represents the value below which a number will be treated as zero (default value is 1e-12). Default value of epsilon is 1e-12.

    Data Types: struct

    Output Arguments

    collapse all

    Axis-angle rotation, returned as a four element row vector. The first three elements specify the rotation axis, and the last element defines the angle of rotation.
