MATLAB: How to create a cell array whose cells are strings based on a sequence of integers 1:N (for any N)

cell arraylegend

I want my function to add a legend to a plot where the legend has a variable number of items depending on N: e.g. '1', '2', '3' if N=3. The help file tells me I can use a matrix or a cell array: legend(M). But I can't find a way of creating a suitable array without fixing the number of cells. For example,
num2cell(1:N)'
doesn't help because legend() only seems to accept cell arrays containing strings, not numeric values. And int2str() doesn't help because it adds spaces in between the numbers.

This works for any MATLAB versions:
>> arrayfun(@num2str,1:3,'Uni',0)
ans = 
    '1'    '2'    '3'
