About Cell arrays access

I have the following question... Suppose I have a cell array given by:

a{1}={'teste' 4},
a{2}={'meste' 5},
a{3}={'zeste' 6},

How could I have access to the letters 't' 'm' and 'z' at the same time. It means, I would like a command line in terms of () [] and {} in such a way I could get these letters (or the numbers!!) and save them in a new variable.

a{1}={'teste' 4},
a{2}={'meste' 5},
a{3}={'zeste' 6},
B = cellfun(@(x) x{1}(1),a)

Actually, I would like to do it withtou cellfun... using only : () [] {}. But Thank you so much anyway

You cannot do it with just () [] {}. You need some form of iteration, or you need at least one anonymous function to help, or you need to assign to at least one variable. (I have been able to do it with two temporary assignments.)
