Is lyapExp working properly?

WHEN I ENTER AT MATLAB PROMPT: lyap = lyapunovExponent(x,50). x is my signal and fs=50 Hz.
I GET THE FOLLOWING LIST OF ERROR MESSAGES:
Not enough input arguments.
Error in rms (line 17)
delta = windowlength - overlap;
Error in enbw (line 33)
bw = (rms(window)/mean(window))^2;
Error in psdparserange>parseTime (line 84)
rbw = enbw(w,fs);
Error in psdparserange (line 35)
[Pxx, F, Frange, rbw] = parseTime(funcName, beta, varargin{1:min(n,3)});
Error in meanfreq (line 63)
[Pxx, F, Frange, rbw, extraArgs, status] = psdparserange('meanfreq',
kaiserBeta, varargin{:});
Error in lyapunovExponent>parseAndValidateInputs (line 199)
MinSeparation = ceil(fs/max(meanfreq(x,fs)));
Error in lyapunovExponent (line 54)
[x, fs, dim, lag, ExpansionRange, MinSeparation, isSingle] =
parseAndValidateInputs(x, varargin{:});

Hi Gerald,
Could you help determine which "rms" command the top error from your error trace is coming from:
Error in rms (line 17)
delta = windowlength - overlap;
When you run the following in the Command Window:
which -all rms
is the top output something like "...matlab\toolbox\signal\signal\rms.m"
It looks like another "rms.m" might be shadowing the ...\signal\rms.m command.
Best Regards,
Bora
