Description

The list of methods to do mean are organized into topic(s).

Method

Doublemean(Double totalValue, int numValues)
Retrieves mean value of the list of floats. 
return numValues != 0 ? totalValue / numValues : 0;
doublemean(double v1, double v2)
mean 
return (v1 + v2) / 2.0d;
doublemean(double values[])
Computes average of the elements of the vector. 
double sum = 0;
for (double value : values)
    sum += value;
return sum / values.length;
Doublemean(Double[] a)
mean 
if (a.length == 0) {
    throw new IllegalArgumentException("The entered array is empty.");
Double sum = 0.0;
for (int n = 0; n < a.length; n++) {
    sum += a[n];
return sum / a.length;
...
doublemean(double[] a)
mean 
return mean(a, 0, a.length);
doublemean(double[] a)
computes the mean of a double array 
double sum = 0;
for (int i = 0; i < a.length; i++) {
    sum += a[i];
return sum / (double) a.length;
doublemean(double[] a)
mean 
return sum(a) / a.length;
double[]mean(double[] a, double[] b)
Returns the mean between two vectors 
if (a.length != b.length) {
    throw new IllegalArgumentException(
            "Error computing mean in Utilities.mean: arrays should have the same length");
double[] sum = new double[a.length];
for (int i = 0; i < a.length; i++) {
    sum[i] = (a[i] + b[i]) / 2;
return sum;
double[]mean(double[] a, double[] b)
average two identical double array 
int n = Math.min(a.length, b.length);
double[] ret = new double[a.length];
for (int i = 0; i < n; i++) {
    ret[i] = (a[i] + b[i]) / 2.0;
return ret;
doublemean(double[] a, int from, int to)
Computes the mean value in the specified range of an array. 
double sum = 0.0;
for (int i = from; i < to; i++) {
    sum += a[i];
return sum / (double) (to - from);
