nums=[1,2,12,121];
out=cellstr(string(nums))

out = 1×4 cell array
    {'1'}    {'2'}    {'12'}    {'121'}

How is that incorrect? And what is the expected output then?

Shouldn't ask the question in the first place had I understood matlab's interesting display.

Apparently: {'1','2'} == {'1'} {'2'} ~= {{'1'}{'2'}} but they are all 1×2 cell array.
