Quaternion Toolbox 1.2.2 Matlab script

Publisher review:
Quaternion Toolbox - Vectorized quaternion functions A set of functions that can operate on quaternions or "vectors" of quaternions (4xN or Nx4 matrices). Available functions are:isq, isnormqqconj, qnorm, qmultqdecomp, qvxform, qvrotq2dcm, dcm2qFor purposes of these tools, a quaternion, q, is just a four element vector where q(1:3) is the "imaginary" or "vector" portion of the hypercomplex number, and q(4) is the "real" or "scalar" portion. Consequently, if q represents a rotation, then:q(1) = v1*sin(phi/2)q(2) = v2*sin(phi/2)q(3) = v3*sin(phi/2)q(4) = cos(phi/2)where phi is the amount of rotation about the unit vector [v1 v2 v3].You may also want to look at the "qlib" Simulink Block Library, available elsewhere in this archive. Requirements: · MATLAB Release: R11.1
Operating system:
Windows / Linux / Mac OS / BSD / Solaris
