for (double d : vector)
 ret += Math.pow(d, 2);
return ret;

double sumOfSquares(double[] vector)
sum Of Squares

double sum = 0;
for (double d : vector)
 sum += sq(d);
return sum;

int sumOfSquares(int numberOfTerms)
sum Of Squares

return (int) (((double) numberOfTerms / 6) * (numberOfTerms + 1) * (2 * numberOfTerms + 1));

double sumOfSquares(Number[] array)
Returns sum of all the squared elements in the array.

double result;
int i;
result = 0.0;
for (i = 0; i < array.length; i++)
 result += array[i].doubleValue() * array[i].doubleValue();
return result;

return sumSq(a, 0, a.length);

int sumSqual(byte[] b)
sum Squal

int sum = 0;
for (int i = 0; i < b.length; i++) {
 sum += (int) Math.pow(b[i], 2);
return sum;

double sumSquared(double[] data)
sum Squared

return sumSquared(data, 0.0);

double sumSquared(double[] data, double term)
sum Squared

double sum = 0.0;
for (int i = 0; i < data.length; i++) {
 if (Double.isNaN(data[i]))
 continue;
 sum += (data[i] + term) * (data[i] + term);
return sum;
