Dear GAP Forum I need a m by n Boolean matrix for saving memory in my works. I know A:=NullMat(m,n); is a Null matrix but I need boolean version. I wrote the following code
B:=[]; for i in [1..3] do Add(B,false); od; A:=[B]; for j in [1..3] do Add(A,B); od; this is the output: gap> A; [ [ false, false, false ], [ false, false, false ], [ false, false, false ], [ false, false, false ] ] and I obtained a null Boolean matrix but if I use the following command A[2][3] := true; I have the following problem gap> A; [ [ false, false, true ], [ false, false, true ], [ false, false, true ], [ false, false, true ] ] I need just A[2][3] := true not A[i][3]. Would you please help me? Best regards Sara _______________________________________________ Forum mailing list Forum@mail.gap-system.org http://mail.gap-system.org/mailman/listinfo/forum
