Problem with matlab curves

Hi, I have a problem please.What we mean by CDF in network. I plot a curve. The abscisse axe represent the users throughput and the vertical axe is the CDF.The question is what is CDF.

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."

thank you for your quiqly response.please what mean by CDF in term of throughput in this document.

Hi, please i have still a problem in matlab. How can i write a code for power control method defined in this paper. Thank you.

[Walter Roberson]

I do not see any reference to power control methods in the discussion that Star Strider posted ?

Hi, My goal is to write a matlab code of the proposed method and the organization chart of the paper. Thanks

[Walter Roberson]

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.
