D.15.11.23 isIntegralSurjective
Procedure from library multigrading.lib (see multigrading_lib).
- Purpose:
- test whether the given linear map P of lattices is
surjective.
- Returns:
- int, where 0 is false and 1 is true.
Example:
| LIB "multigrading.lib";
intmat A[2][3] =
1,3,5,
2,4,6;
// should be 0
int b = isIntegralSurjective(A);
print(b);
==> 0
// another example
intmat B[2][3] =
1,1,5,
2,3,6;
// should be 1
int c = isIntegralSurjective(B);
print(c);
==> 1
kill A, b, B, c;
