Method

voiddivideElements(final int j, final int numRows, final float[] u, final float u_0)
divide Elements 
for (int i = j; i < numRows; i++) {
    u[i] /= u_0;
voiddivideElements4arg(final int j, final int numRows, final double[] u, final double u_0)
divide Elementsarg 
for (int i = j; i < numRows; i++) {
    u[i] /= u_0;
voiddivideElements_Bcol(int j, int numRows, int numCols, double[] u, double b[], int startB, double u_0)
divide Element Bcol 
int indexB = j * numCols + startB;
for (int i = j; i < numRows; i++, indexB += numCols) {
    b[indexB] = u[i] /= u_0;
double[]divideElementwise(int[] a, int[] b)
Divides the values in the two arrays of integers element-wise. 
if (a.length != b.length) {
    throw new ArithmeticException();
} else {
    double[] result = new double[a.length];
    for (int i = 0; i < a.length; i++) {
        result[i] = (double) a[i] / b[i];
    return result;
...
float[][]divideImage(float[][] base, float[][] divisor)
Calculates the value of one image divided by another, pixel by pixel 
float[][] output = new float[base.length][base[0].length];
for (int i = 0; i < base.length; i++) {
    for (int j = 0; j < base[0].length; j++) {
        output[i][j] = base[i][j] / divisor[i][j];
return output;
voiddivideInPlace(double denominator, double[] target)
divide In Place 
for (int i = 0; i < target.length; i++) {
    target[i] /= denominator;
voiddivideInPlace(float[] vector, float val)
Divides the second vector from the first one (vector1[i] /= val) 
int length = vector.length;
for (int i = 0; i < length; i++) {
    vector[i] /= val;
Object[][]divideIntoChunks(Object[] objs, int chunkSize)
Divides an array of Objects into series of smaller arrays. 
Object[][] chunkObjs = null;
if (objs == null || objs.length == 0) {
    chunkObjs = new Object[0][];
} else {
    int chunks = ((objs.length - 1) / chunkSize) + 1;
    chunkObjs = new Object[chunks][];
    int count = 0;
    int batchCount = 0;
...
double[]divideNonSingular(int[] array1, int[] array2)
Divides two arrays element-to-element, but when numerator and denominator = 0, returns 0 instead of a singularity (NaN) 
double[] out = new double[array1.length];
for (int i = 0; i < out.length; i++)
    out[i] = array1[i] == 0 && array2[i] == 0 ? 0 : (double) array1[i] / array2[i];
return out;
voiddivideVector(float[] resultVec, float divisor)
Divide all element of a vector by a scalar 
for (int i = 0; i < resultVec.length; i++) {
    resultVec[i] /= divisor;
