"""
The vector module.

This module provides  mappings to some functions of  gsl vectors as descirebed
in  Chapter  8.3 of  the  gsl reference  document.  All  functions accept  one
dimensional Numeric arrays instead of gsl vectors, or return Numeric arrays.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
   Warning: When translating alghorithms from C to Python, check if the
   functions do the same. Inplace change does not need to have effect here,
   some of  these functions make copies internally.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

All  functions from  Section 8.3.3  take  an integer  as input  and return  an
approbriate Numeric array as output. The prefix gsl_vector has been discarded.
These functions are:
     set_zero
     set_all
     set_basis

Functions to read write the vector from a file are provided as well:
    fprintf
    fscanf
    fread
    fwrite

Some basic data operations are provided as well (See Section 8.3.7):
    reverse      
    swap         
    swap_elements

And some functions from Section 8.3.9    
    max          
    min          
    minmax       
    isnull       
    max_index
    min_index
    minmax_index
