Method

intsumRow(int[][] table, int column)
sum Row 
int sum = 0;
for (int r = 0; r < table.length; r++) {
    sum += table[r][column];
return sum;
double[]sums(double[][] input)
Return an array of the sums for each column in the 2D input 
double[] theSums = new double[input[0].length];
for (int r = 0; r < input.length; r++) {
    for (int c = 0; c < input[r].length; c++) {
        theSums[c] += input[r][c];
return theSums;
doublesumSpecificIndices(double[] input, int[][] indices, int columnInIndices)
sum Specific Indices 
double total = 0;
for (int i = 0; i < indices.length; i++) {
    total += input[indices[i][columnInIndices]];
return total;
floatsumSq(float[][] arr)
Calculate the sum of the squared values of a 2D array. 
float sum = 0;
for (int i = 0; i < arr.length; i++)
    sum += sumSq(arr[i]);
return sum;
