| ### 4.12.3 module operations `+` addition (concatenation of the generators and simplification) `*` multiplication with ideal or poly (but not `module` * `module`!) module_expression `[` int_expression `,` int_expression `]` is a module entry, where the first index indicates the row and the second the column module_expressions `[` int_expression `]` is a vector, where the index indicates the column (generator) Example:
      ring r=0,(x,y,z),dp;
      module m=[x,y],[0,0,z];
      print(m*(x+y));
    ==> x2+xy,0,
    ==> xy+y2,0,
    ==> 0,    xz+yz
      // this is not distributive:
      print(m*x+m*y);
    ==> x2,0, xy,0,
    ==> xy,0, y2,0,
    ==> 0, xz,0, yz
