norm

AnsVec.norm(nrmtype='nrm2')

Return the norm of the AnsMath object.

Parameters:

nrmtypestr, optional

Mathematical norm to use. The default is 'NRM2'. Options are:

• 'NRM2': L2 (Euclidean or SRSS) norm.

• 'NRM1': L1 (absolute sum) norm (vectors only).

• 'NRMINF': Maximum norm.

Returns:

float

Norm of the matrix or the one or more vectors.

Examples

>>> dim = 1000
>>> m2 = mm.rand(dim, dim)
>>> nrm = m2.norm()
