Method Detail

absoluteNorm

public static double absoluteNorm(double[] vectorX)
                           throws java.lang.NullPointerException

Calcula la norma absoluta de un vector. Llamada "norma euclidiana".

absoluteNorm

public static double absoluteNorm(double[] vectorX,
                                  double[] vectorY)
                           throws java.lang.NullPointerException

Calcula la norma absoluta de vectorX - vectorY.

Returns:

0.0 Si no son del mismo taman~o o se anulan

indexOfMaxAbs

public static int indexOfMaxAbs(double[] vectorX)
                         throws java.lang.NullPointerException

Busca el primer elemento mas grande en valor absoluto del vector. Abreviacion de "firstIndexOfMaximumAbsoluteValue".

infiniteNorm

public static double infiniteNorm(double[] vectorX)
                           throws java.lang.NullPointerException

Regresa el valor del maximo elemento del vector. Notacion: || x ||oo (infinite).

dotProduct

public static double dotProduct(double[] vectorX,
                                double[] vectorY)
                         throws java.lang.NullPointerException

Deprecated. multiply

Equivalente a multiply == dotProduct == rowColumnProduct
