How to create a cell of strings from a vector?

I have the vector
x = [ 10.027 20.35 50.1 100.002 ]
which I would like to convert to the cell
x = { '10', '20', '50', '100' }.
How can I do this? I know I can use sprintf('%.0f\n', x) to get the formatting I want, but not how to turn the outputs into a cell of strings.

 Accepted Answer

Encapsulate sprintf() into arrayfun():
arrayfun(@(in) sprintf('%.0f', in), x,'un',0)

Thanks for the speedy and correct answer.
If you don't mind leading spaces:
cellstr(num2str(x','%.0f'))
  • pluses: no arrayfun
  • deltas: leading spaces
Very useful, thanks. I am more likely to recall cellstr next time.
If you add left justify to the format it removes the leading spaces:
cellstr(num2str(x','%-0.0f'))

Perhaps this is faster:
Str = sprintf('%.0f*', x);
C = regexp(Str, '*', 'split');
Based on Sean De Wolski's answer:
cellstr(num2str(x','%-0.0f'))
