int VecNorm(Vec x,NormType type,double *val)Collective on Vec
x | - the vector |
type | - one of NORM_1, NORM_2, NORM_INFINITY. Also available NORM_1_AND_2, which computes both norms and stores them in a two element array. |
NORM_1 denotes sum_i |x_i|
NORM_2 denotes sqrt( sum_i (x_i)^2 )
NORM_INFINITY denotes max_i |x_i|
