D.15.21.39 tensorModFreemod
Procedure from library modules.lib (see modules_lib).
- Return:
- Tensorprodukt of M,F
Example:
| LIB "modules.lib";
ring R = 0,(x,y,z),dp;
matrix a[1][2] = x,y;
Matrix A = a;
matrix b[1][2] = x2,y2;
Matrix B = b;
Module M = subquotient(A,B);
M;
==> subquotient (| x y |, | x2 y2 |)
==>
==>
FreeModule F = freeModule(R,3,0);
F;
==> 3
==> R
==> free Module
==> Degrees of the generators: {0} {0} {0}
==>
tensorModFreemod(M,F);
==> cokernel | 0 0 0 x 0 0 -y 0 0 |
==> | 0 0 0 0 x 0 0 -y 0 |
==> | 0 0 0 0 0 x 0 0 -y |
==> | y 0 0 0 0 0 x 0 0 |
==> | 0 y 0 0 0 0 0 x 0 |
==> | 0 0 y 0 0 0 0 0 x |
