com.irurueta.algebra.InfinityNormComputer

public class InfinityNormComputer
extends NormComputer

Class in charge of computing infinity norms of vectors and matrices. Infinity norm is defined as the maximum row sum on a matrix or vector.

For the case of arrays, this library considers arrays as column matrices with one column and array length rows, hence absolute value of first element in array is returned as infinity norm.
