I plotted sumrate against number of iterations but my data is very noisy. I need a smooth PDF, how can I smooth and normalize the attached noisy data. Thanks.

I have no idea what result you want.
One option is the filloutliers function (or similar functions) and another is the Signal Processing Toolbox sgolayfilt function to do broadband filtering.

It would be interesting to see your sgolayfilt call. I usually use a degree 3 polynomial, begin with a frame length that is about 5% of the length of the vector, and then adjust the framelength until I get the result I want.
There are several smooth functions. I have no idea which one you are referring to.

Please check the smoothdata Matlab function
it can smooth the data in number of ways, note that the trade-off between the actual data points and the averaged data points should be within the acceptable level.
