NAME wnvnrm -- fast vector norm SYNOPSIS #include "wnvect.h" double wn_norm2_vect(double *vect,int len) double wn_norm_vect(double *vect,int len) void wn_unit_vect(double vect,int len) double wn_dist2_vect(double v1[],double v2[],int len) double wn_dist_vect(double v1[],double v2[],int len) DESCRIPTION Vector norm and squared norm, coded to be especially fast. Find unit vector. Vector distance and distance squared. DIAGNOSTICS BUGS SEE ALSO wnvadd, wndot AUTHOR Will Naylor
