| 2016-10-16 16:27:01 +0200 | commented answer | n-th power of matrices Thank you for answering. However, I think you misinterpreted my question. To be clear, in my question n is a variable (as stated), while the matrix I want to calculate the n-th power of is known. I reformulated my question. |
| 2016-10-16 14:28:01 +0200 | asked a question | n-th power of matrices Is there any way to calculate the n-th power of a (upper unitriangular) matrix in Sage? Here n is an integer variable. For example, if y=matrix([[1,0,0],[0,1,1],[0,0,1]]), then I want to obtain a formula in n for y^n. In this case this would be y^n=matrix([[1,0,0],[0,1,n],[0,0,1]]). I tried the following: sage: y=matrix([[1,0,0],[0,1,1],[0,0,1]]); var('n'); sage: y^n This resulted in the error: "NotImplementedError: non-integral exponents not supported" Adding sage: assume(n, 'integer') has no effect at all. |
