Modifier and Type	Method and Description
static double[]	add(double[] vecA, double[] vecB) Adds each element from two vectors and returns the result as a new vector.
static double	length(double[] vec) Calculates the (geometric) length of a vector.
static double[]	max(double[] vecA, double[] vecB) Creates a new vector containing the larger elements from both vectors, that is r[n] = max(a[n], b[n]).
static double[]	min(double[] vecA, double[] vecB) Creates a new vector containing the smaller elements from both vectors, that is r[n] = min(a[n], b[n]).

Method Detail

add

public static double[] add(double[] vecA,
           double[] vecB)

Adds each element from two vectors and returns the result as a new vector.

Returns:

the new vector containing the per element sum

max

public static double[] max(double[] vecA,
           double[] vecB)

Creates a new vector containing the larger elements from both vectors, that is r[n] = max(a[n], b[n]).

Returns:

the new vector containing the larger elements

min

public static double[] min(double[] vecA,
           double[] vecB)

Creates a new vector containing the smaller elements from both vectors, that is r[n] = min(a[n], b[n]).

Returns:

the new vector containing the smaller elements

sum

public static double sum(double[] vec)

Calculates the sum of a vector.

Returns:

the sum of all elements

length

public static double length(double[] vec)

Calculates the (geometric) length of a vector.

Returns:

the geometric length of the vector

normalize

public static void normalize(double[] vec)

Normalizes all elements of a vector.
