## The Operations on the Matrix Function

Cao Shaochen; Jiang Wanli(Mathematics Departinent of Military Economic Academy, Wuhan 430035, China)
Matrix function is defined by matrix series of powers in matrix analysis. The main problem solved is the relationship between the matrix generated by the matrix series of powers and the matrix generated directly by matrix operations such as addition, subtraction, multiplication and inversion, if the matrix function contains operationswhich are addition, subtraction, multiplication and division. The important result is that under certain conditions. Using this result, the calculation of the sum matriX series of powers is easier than other method. In fact, if , convergence radius is R, r(A ) R, then
