2011-09-27 22:50:38 +0200	asked a question	How to get the coefficient of $x^n$ in symbolic expression of matrix I have the symbolic matrix: `x = var('x') h = Matrix(SR, [[x,2],[3*x+5,4]])` How can I get the coefficients of $x^n$ in symbolic expression of matrix. I need to get the follow two matrix from that one: `[[1,0],[3,0]] [[0,2],[5,4]]`
