how to convert Cell to string

Suppose I have a cell

v =    'v'    [576.5818]    [3.0286]    [576.9270]

       'v'    [576.5953]    [3.1180]    [576.8716]

       'f'    [      56]    [    58]    [      52]

       'f'    [      56]    [    58]    [      52]

and I want to convert this to a cell array using a format string for each

element:' %.5f' How can I do this? I tried the following approach, but I get an error:

f1 = @(x) sprintf(' %.5f',x);

cellfun(f1, num2cell(v),'UniformOutput', false)

i am getting an error as ???

Error using ==> sprintf

Function is not defined for 'cell' inputs.

Error in ==> @(x)sprintf(' %.5f',x)

Can any one help me thanks in advance

Modify the command

cellfun(f1, num2cell(v),'UniformOutput', false)

to

cellfun(f1, v,'UniformOutput', false)

[Sharen H]

perfectly it works but the first column value is changed to number instead of 'v'

[Kye Taylor]

Create a function file such as

function write2file(x)
if ischar(x)
  sprintf(' %s',x)
else
  sprintf(' %.5f',x)
end

Then try

cellfun(@write2file,v,'UniformOutput',false)

That is what num2str does automatically...

cellfun(@(x) num2str(x,'%.5f'),v,'un',0)
