Converting an unsigned unit quaternion to rotation matrix on SO(3)
Description
It forms a (3 x 3) rotation matrix on SO(3) from an unsigned unite quaternion in S^3 (the four-dimensional sphere).
Usage
quat2rot(x)
Arguments
x
An unsigned unit quaternion in S^3.
Details
Given an unsigned unit quaternion in S^3 it forms a rotation matrix on SO(3), according to the transformation proposed by Prentice (1986).
Value
A rotation matrix.
