Be specific about the form of your data.
Do you mean that you have a single variable you measured, and you are
talking about peaks of some histogram of the data? Or do you have
x,y data? If the latter, the peak height is just max(y), and the location
is x[y==max(y)]. The width is not too hard; I have a function that finds
