correlation matrix labels

Assume I have:

names = { 'one', 'two', 'three' };

How could i generate the matrix:

'one vs one'    'one vs two'    'one vs three'
'two vs one'    'two vs two'    'two vs three'
'three vs one'  'three vs two'  'three vs three'

(without a nested for loop of course)

Answer 1

[Daniel Shub]

names = {'one', 'two', 'three'};
middle = {' vs '};
N = length(names);
reshape(strcat({names{repmat(1:N, N, 1)}}, middle, {names{repmat(1:N, N, 1)'}}), N, N)'

ans =

    'one vs one'      'one vs two'      'one vs three'  
    'two vs one'      'two vs two'      'two vs three'  
    'three vs one'    'three vs two'    'three vs three'
