You can use the "Visual Incrementing" script from
http://www.erols.com/astronaut/vim/index.html#VimFuncs
to convert a block of numbers selected via ctrl-v (visual block)
into a column of increasing integers. Select the column, press :I<CR>,
and the first line's number will be used as a starting value. Subsequent
lines's numbers will be incremented by one.
If the ctrl-v block is "ragged right", which can happen when "$" is used
to select the right hand side, the block will have spaces appended as
needed to straighten it out. If the strlen of the count exceeds the
visual-block allotment of spaces, then additional spaces will be inserted.
Example: Put cursor on topmost zero, select column with ctrl-v, then :I
vector[0]= 1; vector[0]= 1;
vector[0]= 1; vector[1]= 1;
vector[0]= 1; --> vector[2]= 1;
vector[0]= 1; vector[3]= 1;
vector[0]= 1; vector[4]= 1;
This script works with both vim 5.7 (:so visincr.vim) or vim 6.0 (source it
as for vim 5.7 or drop it into the .vim/plugin directory).

" another way of generating incremented numbers
"=============================================================================
" File: increment.vim
" Author: Stanislav Sitar ([email protected])
" Help:
" Put increment.vim into a plugin directory.
" Use in replacement strings
" :let I=0
" :%s/my_token_word_to_be_replaced_by_the_auto_incremented_numbers/\=INC(1)/
" or
" :let I=95
" :%s/@/\=INC(5)/
" to replace each occurence of character @ with numbers starting with 100 and
" growing by 5 (100, 105, 110, ...)
"
" Instalation: save this text as increment.vim in your plugins directory
"=========================================================================
let g:I=0
function INC(increment)
let g:I =g:I + a:increment
return g:I
endfunction

Visincr.vim has been improved -- it now uses virtual column calculations
which avoid problems with leading tabs -- you may even mix leading
tabs and spaces, incrementing only the visually selected column.

Other methods/scripts for incrementing scripts are available as:
Srinath Avadhanula vimscript#156
Stanislav Sitar vimscript#145
If you're interested in using substitute based approaches, you
might wish to consider Stefan Roemer's <vis.vim>, which allows
one to apply a substitute to just a visual-block. You can get
a copy of his script at
http://www.erols.com/astronaut/vim/index.html#VimVuncs
-- see "Visual Block Commands"

<visincr.vim> supports:
:I<CR> will use the first line's number as a starting point, incrementing by 1
:I #<CR> like :I, but will increment by given number; negative numbers work fine
:II<CR> will pad on left as needed, otherwise like :I
:II #<CR> like :II, but will increment by given number

More features for <visincr.vim>! There's now an additional script, <calutil.vim>,
which adds some calendrical dates <-> Julian day conversion functions. With
those, <visincr.vim> now has new commands:
IMDY [incr] : makes a column of month/day/year dates
IYMD [incr] : makes a column of year/month/day dates
IDMY [incr] : makes a column of day/month/year dates
ID [incr] : makes a column of daynames
Of course, the optional incr (default value is 1) can be positive or negative. Both
scripts are available at http://www.erols.com/astronaut/vim/index.html#VimFuncs.

1. ease of use
2. look at the May 28 note -- visincr handles more than just an incremented/decremented number lists, including dates, roman numerals, alphameric lists, daynames, etc.
3. justification -- visincr's incremented numbers may be either left or right justified
4. zfill (ie. one may have 0s, for example, instead of blanks for a right-justified number list
