### 2.43.13 Kernel of a linear application : `Nullspace`

Warning This function is useful in Maple mode only (hit the state line red button then `Prog style`, then choose Maple and Apply).
`Nullspace` is the inert form of `nullspace`.
`Nullspace` takes as argument an integer matrix of an linear application f with respect to the canonical basis.
`Nullspace`) followed by `mod p` returns a list of vectors that is a basis of the kernel of f computed in ℤ/pℤ[X].
Input :

`Nullspace([[1,1,2],[2,1,3],[3,1,4]])`

Output :

`nullspace([[1,1,2],[2,1,3],[3,1,4]])`

Input (in Maple mode):

`Nullspace([[1,2],[3,1]]) mod 5`

Output :

`[2,-1]`

In Xcas mode, the equivalent input is :

`nullspace([[1,2],[3,1]] % 5)`

Output :

`[2% 5,-1]`
