I want to obtain the function of the curve.....i.e if there is exponential curve...matlab should find the function i.e f=3*e^2

However I would invite you to explore the Curve Fitting Toolbox.

What function there will have "Matlab find the function if there is an exponential curve?" OP may indeed fit an exponential to his data if so inclined, but Matlab won't tell him that that's what's in the plot figure a priori. Now, if he gets a very good correlation and diagnostics don't point out any major fitting issues, it may well be that drawing the conclusion the data follow such a functional form, but Matlab's going to have to have quite a lot of help from the to get to that point.
