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!
