Matrix operations

Prev:	l2-norm ( k -- x )
Next:	p-norm ( k p -- x )

Vocabulary
math.vectors

Inputs

k	a sequence

Outputs

x	a non-negative real number

Generic word contract
Computes the norm (size) of k in 𝑙∞ (L^∞) vector space, usually written ∥･∥∞. For a mathematical vector, this is simply its maximum.

Examples

USING: math.vectors prettyprint ; { 1 2 3 4 } l-infinity-norm .
