Not able to get the matlab equivalent output from tfestimate function (transfer function estimate)

[sarbjit]

Hi,

I am having a program which is written in Matlab. When I am trying to run
that program in Octave, I am not getting the results as seen in Matlab.

Syntax for tfestimate in Matlab is :
[Txy,F]=tfestimate(x,y,window,noverlap,nfft)

Syntax for tfestimate in Ocatve is :
[Pxx,freq]=tfestimate(x,y,Nfft,Fs,window,overlap,range,plot_type,detrend)

As you can see the order of parameters in Octave are different from that of
Matlab. But I am not able to get the expected results from Ocatve even with
modifying the order in the code in the Octave.

Snippet from the Matlab code :
[txy W]=tfestimate(x,y,10,[],[]);

So as per Matlab documentation
(http://www.mathworks.in/help/signal/ref/tfestimate.html), third argument is
window function (which is specified as value of 10), fourth and fifth
argument are noverlap and nfft.

I am not able to modify the code as per the octave specification. Appreciate
if some one would help me to get the expected results.

I am uploading the .mat files for variable vectors (x and y) generated from
Matlab. This file can be loaded as :
load -mat-binary x.mat
load -mat-binary y.mat
[txy W]=tfestimate(x,y,10,[],[]); %MATLAB version
plot(W,abs(txy))

If you plot this in Matlab, curve will be varying while in Octave it will be
a straight line. (Uploading the outputs as well).

Thanks in advance for help
