norm

AnsMath.norm(obj, order='nrm2')

Return the norm of an AnsMath object.

Parameters:

objAnsMat or AnsVec

AnsMath object to compute the norm from.

orderstr

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.

nrmfloat

Norm of the matrix or the one or more vectors.

Examples

Compute the norm of an AnsMath vector.

>>> v = mm.ones(10)
>>> print (mm.norm(v))
>>> 3.1622776601683795
