Method Detail

• public static double distance(double[] p1, double[] p2)

  Computes the distance between two points. If the dimensions of p1 and p2 are unequal, this method returns a NaN.

  Parameters:

  p1 - coordinates of point 1

  p2 - coordinates of point 2

  Returns:

  distance between the points

• public static double erf(double x)

  Error function. Approximation based on Press et al, Numerical Recipes in Fortran 77: The Art of Scientific Computing (1992), p214.

  Parameters:

  x - real argument

  Returns:

  value of the error function

• public static double erfc(double x)

  Complementary error function. Approximation based on Press et al, Numerical Recipes in Fortran 77: The Art of Scientific Computing (1992), p214.

  Parameters:

  x - real argument

  Returns:

  value of the complementary error function

• public static double erfcinv(double x)

  Inverse complementary error function. Approximation based on Giles (2010).

  Parameters:

  x - argument between 0 and 2

  Returns:

  value of the inverse complementary error function

• public static double erfinv(double x)

  Inverse error function. Approximation based on Giles (2010).

  Parameters:

  x - argument between -1 and 1

  Returns:

  value of the inverse error function
