Hello every body, To resolve my problem I used this Code for a simple example: A = {{1 + x, 2 + x}, {3 + 2 x, 1 + 2 x}}; Ainv = Inverse[A]; B = {{1 - x, 1 + 2 x}, {1 + 3 x, 1 + x}}; M = {1, 0}; Print["With LinearSolve "] LinearSolve[A, B . M] Series[%, {x, 0, 1}] /. x -> 0 Print["With Inverse "] Factor[Ainv . B. M] Series[%, {x, 0, 1}] /. x -> 0 I find the same result from LinearSolve and Inverse Methods and I think that I can use it for and order >2. What do you think dear math group. Lian.
