I'd like to invert a matrix whose dimensions are specified only symbolically, but I'm not sure how to represent it in Mathematica (or if Mathematica can do it). The matrix is: a b b^2 ... b^k b a b ... b^(k-1) b^2 b a ... b^(k-2) .. . .. . .. . b^k b^(k-1) ... a I tried representing this matrix as a list, using symbols in Table[], but Mathematica won't evaluate the bounds when they are symbolic. Is there a way to do this? Any ideas would be greatly appreciated!!! Thanks. Jon Davis jondavis at uiuc.edu
