cell array, add suffix to every string

Question

Suppose I have a cell array containing strings:

c = {'foo1', 'foo2', 'foo3'}

I now want to add the same suffix "bar" to each string, such that the cell array becomes:

c = {'foo1bar', 'foo2bar', 'foo3bar'}

Is there a shortcut to doing this, without explicitly looping through each element?

strcat operates on cell arrays:

>> c = {'foo1', 'foo2', 'foo3'}
c = 
    'foo1'    'foo2'    'foo3'
>> c2 = strcat(c,'bar')
c2 = 
    'foo1bar'    'foo2bar'    'foo3bar'

What about using cellfun:

c=cellfun(@(x) strcat(x, 'bar'), c, 'Uniformoutput', 0);

I don't know if it's faster to run than a loop, but it's less tedious to write.

Edit: apparently strcat handles cell arrays. Use cellfun for functions that don't.
