Description

The list of methods to do Array Value Dot Product are organized into topic(s).

Method

Double[] arrayDot(final Double[] first, final Double[] second)
multiplies the elements of the arrays.

final Double[] toret = new Double[first.length];
for (int i = 0; i < first.length; i++) {
 toret[i] = first[i] * second[i];
return toret;

String[] arrayDot2Zero(String[] values)
array Dot Zero

int count = values.length;
String[] results = new String[count];
for (int index = 0; index < count; index++) {
 if (values[index].equals(".")) {
 results[index] = "0";
 } else {
 results[index] = values[index];
return results;

double[] arrayMultiplication(double[] a, double[] b)
Elementwise multiplication of arrays

if (a == null || b == null) {
 return null;
if (a.length != b.length) {
 throw new ArrayStoreException("Array sizes do not match.");
if (a.length == 0) {
 throw new ArrayStoreException("Array of length zero.");
...

double[] arrayMultiply(double[] a, double[] b)
Multiplies two vectors of doubles, array-wise.

double[] out = new double[a.length];
for (int i = 0; i < a.length; i++) {
 out[i] = a[i] * b[i];
return out;

int arrayProduct(int[] vs)
array Product

int result = 1;
for (int i = 0; i < vs.length; i++) {
 result *= vs[i];
return result;
