Dear Forum,
I have a matrix of transformations:
[[Transformation([1,2]),Transformation([2,2])],
[Transformation([2,2]),Transformation([2,2])],
[Transformation([1,2]),Transformation([2,1])]]
and I want to replace
[Transformation([1,2]) by 1;
[Transformation([2,2]) by 2;
[Transformation([2,1]) by 3
A rather simple way is to use `Position':
t:=[Transformation([1,2]),Transformation([2,2]),Transformation([2,1])];
matn:=List(mat,i->List(i,j->Position(t,j)));
Best,
Alexander Hulpke
