Hi, let me dive straight into my problem wit a simple example:
>> a = identity_matrix(ZZ,2,2) >> a[0,0] 1 vs. >> a[:,0] [1] [0] >> a[:,0][0] (1) So when selecting an element from a matrix by first selecting a row and selecting the wanted element in that new 'row object', I don't get an element from ZZ but a FreeModuleElement. Why is this happening? Is there a way to make my two actions behave like selecting an element from the original matrix?
