Method Details

norm

public static <T extends Ring<T>> double norm(T... src)

Computes the 2-norm of a vector.

Parameters:

src - Entries of the vector (or non-zero data if vector is sparse).

Returns:

The 2-norm of the vector.

norm

public static <T extends Ring<T>> double norm(T[] src,
 double p)

Computes the p-norm of a vector.

Parameters:

src - Entries of the vector (or non-zero data if vector is sparse).

p - The p value in the p-norm.
- If p is Double.POSITIVE_INFINITY, then this method computes the maximum/infinite norm.
- If p is Double.NEGATIVE_INFINITY, then this method computes the minimum norm.
Warning, if p is large in absolute value, overflow errors may occur.

Returns:

The p-norm of the vector.
