Usage

• Norm[expr] gives the norm of a number or array.
• Norm[expr, p] gives the -norm.

Notes

• For complex numbers, Norm[z] is Abs[z].

• For vectors, Norm[v] is Sqrt[v . Conjugate[v]].

• Norm[v, p] is Total[Abs[v^p]]^(1/p).

• Norm[v, Infinity] is the

-norm given by Max[Abs[v]].

• For matrices, Norm[m] gives the maximum singular value of m.

• Norm can be used on SparseArray objects.
