Procedure from library modules.lib (see modules_lib).
- Return:
- Subquotient M converted to coker(C)
Example:
| LIB "modules.lib";
ring R = 0,(x,y),dp;
matrix a[1][2] = x,y;
Matrix A = a;
matrix b[1][2] = x2,y2;
Matrix B = b;
Module M = subquotient(A,B);
presentation(M);
==> cokernel | 0 x -y |
==> | y 0 x |
