about joining arrays with strings and numbers

Hello,

This might be a simple problem but I haven't been able to find any help online. Ok I have two arrays:

A = [1 2 3 4];
B = ['cat' 'dog' 'bird' 'cow'];

what i want to do is something like this:

AB = [1 2 3 4
         cat dog bird cow]

but matlab is not letting me do this because one is a set of numbers and the other is a set of strings

any help?
cheers,
S.

You may want to use cells:

a = {1 2 3 4};
b = {'cat' 'dog' 'bird' 'cow'};
ab = [a;b]

ab =
    [ 1] [ 2] [ 3] [ 4]
    'cat' 'dog' 'bird' 'cow'

For example, column 2 gives:
ab(:,2)
ans =
    [2]
    'dog'

You'll have to use cell arrays:
B = {'cat' 'dog' 'bird' 'cow'}
AB = [{A};{B}];

or
A = {1 2 3 4};
AB = [A; B];

depending on what you want
