Abstract:
This research proposes a double-base vector representation system. We focus on four-dimensional vector space, called quaternion system. The representation of quaternion system contains one real number and three unit vectors, which are denoted by i, j, and k Although the vector is used in many application (i.e., mechanics, physics, signal processing, electrical), the computation of vector is very slow. By adapting the concept of double-base for vector representation, two vectors are proposed as the bases for representing the quaternion system. We prove that four-dimensional vectors can have representation in the proposed double-base quaternion system. Fundamental arithmetic operations for quaternion system are also introduced, including addition, subtraction and multiplication. Moreover, using the proposed quaternion system the vector operations can be processed in parallel manner.
