I just used the following commands to construct an matrix: q = 2 r = 2 s = 2 n = s*(r+1) d = 3 P = matrix(ZZ, r+2, r+2, lambda u, k: Krawtchouk(r+1, q, k, u))
But sage gives me two different results at different times: [ 1 3 3 1] [ 1 1 -1 -1] [ 1 -1 -1 1] [ 1 -3 3 -1] and [ 1 3 3 1] [ 1 0 -3 -1] [ 1 -3 3 1] [ 1 -3 3 -5] The upper matrix is the right one. But sometimes I get the lower matrix. Anyone knows why this happens? Thanks :) -- You received this message because you are subscribed to the Google Groups "sage-support" group.
