9b16348 fixed CreateHomalgMatrixFromSparseString for MAGMA Hallo Mohamed, das hat wahrscheinlich noch nie funktioniert, denn homalg_variable_5 ist eine Liste rationaler Zahlen. Die ersten beiden Einträge müssen wir erst nach Z konvertieren. Das hier sollte gehen. homalg_variable_6 := Matrix(SparseMatrix(homalg_variable_1,2,2, [car< Integers(), Integers(), homalg_variable_1 > | <a,b,c> where a,b,c:= Explode(e): e in homalg_variable_5] )); Viele Grüße Markus On Monday, April 17, 2017, 3:35:12 PM GMT+2, Mohamed Barakat <mohamed.barakat@uni-siegen.de> wrote: Lieber Markus, dieser Code scheint nicht mehr zu funktionieren: https://github.com/homalg-project/homalg_project/blob/master/RingsForHomalg/gap/MAGMA.gi#L899 Auf der MAGMA Seite erzeugt er folgende Aufrufe: $ magma homalg_variable_1 := Rationals(); homalg_variable_5 := [ [ 1, 1, 1/3 ], [ 1, 2, 1/4 ], [ 2, 1, 1/5 ], [ 2, 2, 1/6 ] ]; homalg_variable_6 := Matrix(SparseMatrix(homalg_variable_1,2,2, [<a,b,c> where a,b,c:= Explode(e): e in homalg_variable_5] )); <Source not available> Runtime error in 'SparseMatrix': Universe of sequence must be car<Z, Z, R> for some ring R Siehst Du auf Anhieb woran das liegt?
