# Block by block CCDF and PAPR analysis in MATLAB

There are few signals (OFDM-like modulation scheme with uniformly distributed data source) generated by my script. I need to compare scheme performance in sense of CCDF (Complementary Cumulative Distribution Function) and PAPR (Peak to Average Power Ratio). There are MATLAB build-in system object comm.CCDF, and it seems that it needs a full sequence for analyze process. But my signals are generated block by block (for example block may contain $${10}^5$$ frames each of 1024 samples). The whole sequence may contain over $${10}^6$$ blocks, and i need to reallocate memory just to prevent run out.

Is there any way for my sequence to be analyzed block by block to get PAPR and CCDF properties of the whole sequence?
