[MATLAB毕业设计] 程序运行结果有点问题，请求帮忙

[srfxz]

运行结果应该是一个矩阵和一个误码率BER(n)，但实际运行完只剩矩阵，帮忙看程序那出现问题了
程序有好几个上传不方便，希望有好心人能帮我，下周就答辩了。QQ317885381

% FUNCTION 8.5 : "cp0801_PPMreceiver"
%
% Simulates the receiver for 2PPM TH UWB signals
% and computes the average BER
% 'R' is an array containing different waveforms
% of the received signal.
% 'mask' is the waveform of the correlation mask
% 'fc' is the sampling frequency
% 'bits' is the binary stream generated by the source
% (it is the same stream for all the waveforms in 'R')
% 'Ns' is the number of pulses per bit
% 'Ts' is the average pulse repetition period [s]
%
% The function returns the binary stream after the
% detection process ('RXbits') and the vector 'BER'
% containing the average bit error rates for all
% the signals in the input array 'R'.

这个程序如果把*********以下的程序删了，运行结果没有改变
