Identification of Cramer Ruler over Quaternion Field by Using Two Different Methods
Shuhai Li · Journal of Yanan University · 2012
It is discussed that the solution of linear equations in n variables over quaternion field can be simplified into the solution of linear equations in 2n variables over complex field.Therefore,Cramer ruler is to be proven respectively by two different methods.Thus the property of some determinants over complex field is obtained by introducing a sign from a class of determinants.
