How do I export data from plotted graph to excel?

I'm getting graph from analog output by using serial com from arduino to matlab, and the data is stored in workspace. Is there any method to export my data at workspace to excel ?

doc xlswrite

NB: You'll do better if at all possible to wait until you've got all the data before writing a file; sequential adding a value one-at-a-time is going to be very high overhead and you'll have to manually compute the cell location(s) to write each pass.

All in all, why use Excel at all?
