Basis for the null space of a matrix
MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.
MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.
linalg::nullspace(A) returns a basis for
the null space of the matrix A,
i.e., a list B of
linearly independent vectors such that
and only if
a linear combination of the vectors in B.
The component ring of the matrix
A must be
a field, i.e., a domain of category
If the component ring of
A does not have
a canonical representation of the zero element, it can happen that
not find a basis for the null space. In such a case, a wrong result
The kernel of the matrix:
A := Dom::Matrix(Dom::Real)( [[3^(1/2)*2 - 2, 2], [4, 3^(1/2)*2 + 2]] )
is one-dimensional, and a basis is :
A matrix of a domain of category
List of (column) vectors of the domain
R is the component ring of
