array of strings from an array of integers

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

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 ;-)

A = randi(999, 1, 5)

A = 1×5

440 755 70 554 220

plot(1:5, 1:5, 'o-')
xticks(1:5)
xticklabels(compose('%d',A))  %needs R2016b or later

yticklabels(sprintfc('%d', A))   %undocumented
