Method Detail

computeModule

public static float computeModule(float[] vector)

A simple method to compute the module of a vector of size 2.

Parameters:

vector - The vector whose module is requested.

Returns:

The requested module.

computeModule

public static float computeModule(float[] p1,
                  float[] p2)

This method computes the square root of the square distance.

Parameters:

p1 -

p2 -

Returns:

The square rooted distance between two points.

floatFuzzyMath

public static float floatFuzzyMath(float value)

This method ensures that the given value is not equal to 0, returning the same given value if it is not equal to zero or a very small value otherwise.

Parameters:

value -

Returns:

The value itself or a very small positive value otherwise.

squareModule

public static float squareModule(float[] p1,
                 float[] p2)

A method to compute the square distance between two points.

Parameters:

p1 - The first point.

p2 - The second point.

Returns:

The square distance.
