public interface VectConst
extends java.lang.Cloneable, java.io.Serializable

Vector operations that do not change the state of the vector

Method Summary

Vect	clone()
double	dot(VectConst other) Return the Cartesian dot product of this vector with another vector (not including any inverse covariance).
double	magnitude() This is the dot product of the vector with itself premultiplied by the inverse covariance.

Method Detail

dot

double dot(VectConst other)

Return the Cartesian dot product of this vector with another vector (not including any inverse covariance). [Feel free to normalize by the number of elements in the array, if the inverse convariance is defined consistently.]

Parameters:

other - The vector to be dotted.

Returns:

The dot product.

magnitude

double magnitude()

This is the dot product of the vector with itself premultiplied by the inverse covariance. If the inverse covariance is an identity, then the result is just the dot product with itself. Equivalently,

      Vect vect = (Vect) this.clone();
      vect.multiplyInverseCovariance();
      return this.dot(vect);
      

But you can usually avoid the clone.

Returns:

magnitude of vector.
