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
