minRowIndex returns INT, but one of subMatrix's signature is: [1] (D1,List(PositiveInteger),List(PositiveInteger)) -> D1
That means subMatrix can't take matrices that with negative index. One way is to fix subMatrix to let it take LIST INT as arguments, but I want to go with the other way. I doubt the usefulness of arbitrary indexed matrix, aka IndexedMatrix. It is not used anywhere in FriCAS. I think we should only use 1-indexed matrix, that simplifies a lot when writing spad: no need to consider the possibility of IndexedMatrix. Do you agree we should remove minRowIndex (and similar functions) from matrix related domains and categories? -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
