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.

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

[K E]

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');

Nifty!

Based on Sean De Wolski's answer:

 cellstr(num2str(x','%-0.0f'))
