How to fit a CDF function on a dataset?

Hello dear all,

I have a data set of X and Y that its scatter is shown below. I need to fit a CDF function on it. Is there any way to do it in MATLAB?

X = 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 0.5 0.55 0.6 0.65 0.7 0.75 0.8

Y = 0 0.005 0.04 0.12 0.26 0.44 0.61 0.76 0.86 0.926 0.96 0.98 0.99 0.996 0.998 0.999 0.9997

Thanks
