摘要
给出了四元数矩阵平方保持右(左)星序关系、星序关系的完整刻画,并得到了在减序条件下含EP矩阵的四元数矩阵平方的Lwner偏序、减序的刻画。
The comprehensive description about squares of quaternion matrices maintaining(right-,left-) star partial order relation is presented.Moreover,under the condition of minus partial order,the description about Lwner partial order and minus partial order of squares of quaternion matrices which contains EP matrix.
