https://en.wikipedia.org/wiki/Cumulative_distribution_function
"In probability theory and statistics, the cumulative distribution function (CDF, also cumulative density function) of a real-valued random variable X, or just distribution function of X, evaluated at x, is the probability that X will take a value less than or equal to x."

Ah, I overlooked the link to the paper "A Novel Downlink Power Control Scheme in LTE Heterogeneous Network " that you had posted. The paper does say,
"Fig. 4 shows the downlink throughput CDFs (Cumulative Distribution Function) of the macro users in the central cell. "
so their use of CDF is the same as what was already posted.
None of the regular volunteers are willing to code up entire research papers for people, but if you have specific questions about MATLAB then we are willing to assist you in understanding MATLAB features and error messages.
