Thanks for prompt reply.However,I am sorry because I am really new to matlab, can I have a clear instruction on how to create the model.I have no idea on what I can do with the equation.

I am sorry I think you get me wrong.The problem is about image processing not mathematic.I need to read in an image and generate the Rayleigh noise model from the image given that the noise is model by the pdf as written in the link below http://www.bioen.utah.edu/wiki/index.php?title=Noise_modeling_and_Probability_Theory ...pls help..thx
