How to seperate serial data into separate columns

HI all,
I am acquiring serial data from a three axis accelerometer (ADXL345) connected to an arduino. I can successfully read the serial data into matlab using using the 'fgets' function (after opening the com port etc). However, my data which is formatted as x,y,z, is coming in a single column for example -3,-21,28.
How would I go about separating this data into separate columns for further analysis.
Thanks in advance,

Hi KSSV and KL,
thanks both for your answers,
I have attached my code, as i think my understanding isn't good enough to just implement suggestions.
Should i be storing my serial data (s) as a separate value ? As i've realised my for loop is just over writing the same value each time.
thanks again,

your_cell_array = {'21.0,12.232,43';'21.0,12.232,43';'21.0,12.232,43'}
new_cell_array = regexp(your_cell_array, ',', 'split')
