NullSpace

NullSpace[m]
gives a list of vectors that forms a basis for the null space of the matrix m.

Details and OptionsDetails and Options

  • NullSpace works on both numerical and symbolic matrices.
  • The following options can be given:
  • MethodAutomaticmethod to use
    Modulus0integer modulus to use
    ToleranceAutomaticnumerical tolerance to use
    ZeroTestAutomaticfunction to test whether matrix elements should be considered to be zero
  • NullSpace[m,Modulus->n] finds null spaces for integer matrices modulo n.
  • NullSpace[m,ZeroTest->test] evaluates to determine whether matrix elements are zero.
  • Possible settings for the Method option include , , and . The default setting of Automatic switches among these methods depending on the matrix given.
