Detailed Description

template<class T>
class vnl_vector< T >

Mathematical vector class, templated by type of element. The vnl_vector<T> class implements one-dimensional arithmetic vectors to be used with the vnl_matrix<T> class. vnl_vector<T> has size fixed by constructor time or changed by assignment operator. For faster, non-mallocing vectors with size known at compile time, use vnl_vector_fixed* or vnl_T_n (e.g. vnl_double_3).

NOTE: Vectors are indexed from zero! Thus valid elements are [0,size()-1].
