Vector Normalize

Description

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

Method

double vectorNorm(double[] v)
vector Norm

double res = 0.0;
for (double elem : v) {
 res = res + elem * elem;
return Math.sqrt(res);

double vectorNorm(double[] vector)
vector Norm

return Math.sqrt(vectorDotProduct(vector, vector));

double vectorNorm(final double[] vector)
Returns the norm of a vector.

if (vector == null) {
 throw new NullPointerException("Null vector@vectorNorm!");
double temp = 0;
for (int i = 0; i < vector.length; i++) {
 temp += vector[i] * vector[i];
return Math.sqrt(temp);
...

float vectorNorm(float[] v)
Calculate the norm of a vector

float result = 0;
for (float aV : v) {
 result += aV * aV;
result = (float) Math.sqrt(result);
return result;

double[] vectorNormalize(double[] v)
Normalizes the given vector.

double[] result = new double[v.length];
double sum = 0;
for (double d : v) {
 sum += d;
for (int i = 0; i < v.length; i++) {
 result[i] = v[i] / sum;
return result;

float[] vectorNorms(boolean[] in, int veclen)
vector Norms

float[] out = new float[in.length / veclen];
for (int i = 0, k = 0; i < out.length; i++) {
 out[i] = 0;
 for (int j = 0; j < veclen; j++, k++)
 if (in[k])
 out[i] += 1;
return out;
