For this we need to think about definitions. My first impulse is to say that leaf is node with no children, so in particular not empty... > > fix recursive 'has' expression: > > https://github.com/oldk1331/fricas/commit/fe22bec00c0cf0739dd6a9c4991af7b7eeffb7ef.patch I must admit that at first glance this one looks risky. > fix documentation in aggcat.spad: > > https://github.com/oldk1331/fricas/commit/2be927aabf94ca05be45444027c12ef5172cd122.patch AFAICS '==' in original was used to get valid Spad function definition. I am not sure if we want to replace this by '='. In setchildren! : (%, List %) -> % ++ setchildren!(u, v) replaces the current children of node u - ++ with the members of v in left-to-right order. + ++ with v. the orignal version is more verbose, but may be clearer than the shorter one. > > support 'paren' and 'box' in definite integration: > > https://github.com/oldk1331/fricas/commit/a860679c40f896482ee88554cf0a8e0435f2f90b.patch > > support 'paren' and 'box' in 'limit': > > https://github.com/oldk1331/fricas/commit/1a7f813619dd0c58e42ce6a37285aca6f00d116e.patch > We should have some some design telling us what 'paren' and 'box' are supposed to do. Otherwise we risk getting mystery code that nobody knows what it is doing and if what it is doing is right or wrong. -- Waldek Hebisch -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
