Thanks everyone for your earlier help. I have to plot a histogram of values lets say [0.5,0.6,0.8,0.9].I guess the histogram would show an exponential decay ie, the laplacian curve.
I need to find the \lambda parameter of this curve . So please tell me if it be done through http://matplotlib.sourceforge.net/and are there any other libraries which can be used. Thanks in advance. Aditya
