Wikipedia says that "The kernel of a matrix, also called the null space, is the kernel of the linear map defined by the matrix." So maybe Prime's "ker" function (or its "jacobi_symbol" function) is related to the "nullspace" you refer to, since Prime's doc says that they are related to the "kernel" of a matrix (whatever that means).

It seems that above nullspace(mat) code is equivalent to
-transpose(ker(mat))
