Why matlaab shows the error like >>>>> Error in fofdmn1 (line 81) [~,~,paprFOFDM] = PAPR(txSigFOFDM);

I have used the Loop>>> PAPR = comm.CCDF('PAPROutputPort', true, 'PowerUnits', 'dBW'); [~,~,paprFOFDM] = PAPR(txSigFOFDM); disp(['Peak-to-Average-Power-Ratio for F-OFDM = ' num2str(paprFOFDM) ' dB']);
Error message: Array formation and parentheses-style indexing with objects of class 'comm.CCDF' is not allowed. Use objects of class 'comm.CCDF' only as scalars or use a cell array.
Error in fofdmn1 (line 81) [~,~,paprFOFDM] = PAPR(txSigFOFDM);

Exactly the same reason as before.
In your R2015a version, in every case in which the routine you are offering has a step() method, you need to convert
variable(values)
to
step(variable, values)
You need to stop looking at the examples for releases later than yours. I posted the link to the R2015a documentation already.
Every time you see a "Array formation and parentheses-style indexing with objects ..." message, you should be switching to use step()
