I understand that for the identity matrix there are other methods. But I do get the same error message for simply matrix(2) which according to the manual matrix?, should give me the 2by2 zero matrix. Or I get the same error when I try to construct a matrix out of vectors. This should not happen. I have my sage running in ubuntu 12.10 inside a virtual machine and I am using the version 5.3 of sage
Size and empty list of entries: sage: matrix(2, []) [0 0] [0 0] #Rows and #columns: sage: matrix(2, 2) [0 0] [0 0] sage: matrix(2, 3) [0 0 0] [0 0 0] #Rows and list of entries sage: matrix(2, [1, 0, 2, 0, 1, 2]) [1 0 2] [0 1 2] #rows, #columns and list of entries sage: matrix(2, 3, [1, 0, 2, 0, 1, 2]) [1 0 2] [0 1 2] #rows, #columns and a function to supply elements sage: matrix(6, 4, lambda i, j: i+j) [0 1 2 3] [1 2 3 4] [2 3 4 5] [3 4 5 6] [4 5 6 7] [5 6 7 8] Hope it helps, johan -- You received this message because you are subscribed to the Google Groups "sage-support" group.
