2.By using generalized inverses of matrix,quaternion matrix equation AXB+CWD=E which contains two unknown matrices is studied.
3.The Hermitian Least-square Solution of the Quaternion Matrix Equation AX=B
4.It is studied factorizing a matrix over quaternion field to the product of two self-conjugate matrices. And some useful results are obtained.
5.Then, the follows are gotten: the existence of Jordan form main matrices which are similar to a square matrix, and a necessary and sufficient condition of a matrix similar to a diagonal matrix, and the real coefficient minimum polynomial of a matrix.
6.Generalized Schmidt Decomposition of Quaternion Matrix and the Generalized Orthonormalization of a Set of Vectors in a Generalized Unitary Space
7.Firstly, concepts on the interval number, interval numbers decision matrix of experts and a method of nomalizing the decision matrix are introduced.
8.In this paper,with the experiment in color image databases,it is shown that the SVs contain little information of color image and most important information is contained in the two quaternion unitary matrices of SVDQ.
9.We also give the matrix forms of the interface partial derivative with multiple complex interfaces.
