What's the best way to add semi-colons after each element of a matrix?

Hi all,

I have a cell matrix which contains strings like this (showing part of the cell, actual cell can be quite large):

example =

    3×1 cell array      

      {'0           0         0.1   0.0016892         0.2   0.0068476         0.3   0.0016477'  }
      {'0.4 -8.2671e-05         0.5 -0.00012313         0.6 -0.00016255         0.7  -0.0002006'}
      {'0.8 -0.00023696         0.9 -0.00027131'                                                }

I would like to add semi-colons after each element, so the matrix becomes:

      {'0,           0,         0.1,   0.0016892,         0.2,   0.0068476,         0.3,   0.0016477,'  }
      {'0.4, -8.2671e-05,         0.5, -0.00012313,         0.6, -0.00016255,         0.7,  -0.0002006,'}
      {'0.8, -0.00023696,         0.9, -0.00027131,'                                                }

I know I can probably write a for-loop to do it, but it seems very inefficient since I'll need to deal with each element? So what's the most efficient way to add semi-colon after each element?

Many thanks!

>> D = regexprep(C,'\S+','$&,');
>> D{:}
ans = 0,           0,         0.1,   0.0016892,         0.2,   0.0068476,         0.3,   0.0016477,
ans = 0.4, -8.2671e-05,         0.5, -0.00012313,         0.6, -0.00016255,         0.7,  -0.0002006,
ans = 0.8, -0.00023696,         0.9, -0.00027131,

This is elegant, thanks!
