关于复数域的建立,有多种方法,本文的目的是要用二阶矩阵建立复数域,并讨论: 1.复数域包含实数域为子域。 2.方程X~2+1=0在复数域内有解。
There are many ways to set up complex numbers. The purpose of this paper is to set up complex numbers with second-order matrices and to discuss: 1. Complex numbers contain real numbers as sub-domains. 2. The equation X ~ 2 + 1 = 0 has solutions in the complex number domain.
