serial communication data shifted

Hello I'm trying to read analog inputs from arduino and send them to matlab, My problem is that sometimes the data is shifted. I'm erading several analog inputs. When I plot the second input's data, I sometimes get the data from input 1, then I find input 2's data in the plot of input 3. There seem to be a synchronization issue, how can I fix it?

I suggest you debug this by sending the sensor number and the current sample count along with the sensor reading. This will allow you to see whether the data is all being transmitted but sometimes out of order, or if the problem is that entire chunks of data are being missed.
