Hi if I have an array of integers like this:
A=[123 456 789]
How do I get an array of strings, say named B, such that:
BB(1) = 123 (this is string 1) BB(2) = 456 (this is string 2) BB(3) = 789 (this is string 3)
What I am trying to do is use integer values as labels for my xtick labels, and cannot figure out how to do it. Thank you.

The output would have to be a cell array
>> BB=arrayfun(@(a)num2str(a),A,'uni',0)
BB =
'123' '456' '789'
>> BB{1}, BB{2}
ans =
123
ans =
456

Ran in:
If you're using a release that supports the string array (which did not exist when the original question was asked) use string.
A = randi(999, 1, 5)
A = 1×5
790 270 251 663 335
plot(1:5, 1:5, 'o-')
xticks(1:5)
xticklabels(string(A))

xticklabels() as a function did not exist when the question was originally asked either ;-)

xticklabels(compose('%d',A)) %needs R2016b or later
yticklabels(sprintfc('%d', A)) %undocumented
