Plot Bit Error Rate (BER) in log domain
Signal to noise ratio, in dB
Bit-error rate
Format string, as for plot function
Waveform object or string identifying the waveform type (e.g. 'bpsk', 'qpsk', ...)
This is just a call to standard plot function, followed by setting the log flag to 'nl' (logarithmic view of the BER).
