Method Detail

norm

double norm(double[] x)

Used to compute the norm \( \Vert X \Vert \) in the Gram-Schmidt implementation. If this function is not implemented, the \( L_2 \) norm is used.

Parameters:

x - input double vector for which the norm will be computed.

Returns:

a double, the value of the norm of x.
