Prony Toolbox is a GUI to perform Prony analysis.

File Information

We have designed a software tool in MATLAB, the Prony Toolbox, to perform Prony analysis. Prony Toolbox (PTbox) is designed based on several considerations including data preprocessing, model order selection, model order selection criteria, signal subspace selection, signal and noise separation, root inspection and assessing residuals. The PTbox provides flexibility to compare and display analysis results simultaneously for several parameter variations.

Installation Instructions:
- Download the Prony Toolbox Zip file
- Copy the "Prony Toolbox" folder from the CD to the user's machine.
- Use Set Path... option in File menu of MATLAB to add the path of the "Prony Toolbox" folder.
- Prony Toolbox can be started by entering pronytool at the MATLAB command prompt.

Currently I am using Pronytool and I am facing one problem in understanding of Model order and residue selection. And also if I want to use one frequency for one case then how should i choose from multiple frequency for higher order model.

Thanks in advance

Hi,I have a problem with importing the time-domain signal in Prony toolbox,How can I Import my desired signal to it, and get the damping ratio and frequency of system modes. I am getting the following errors.:
Error using evalin
Undefined function 'mmv2struct' for input arguments of type 'struct'.

Error in pronyanalysistool>push_importdata_Callback (line 122)

Error in gui_mainfcn (line 96)

Error in pronyanalysistool (line 42)
gui_mainfcn(gui_State, varargin{:});

Error while evaluating uicontrol Callback

Undefined function 'pronyanalysistool' for input arguments of type

Thanks for sharing,,,,

what is data that must be imported to the pronytool ?
Can anybody help me to send the example of the data...

I need matlab code for parameter estimation of harmonic signal by prony method.

Hi, I played with the pure_demo.
D:\Program Files\MATLAB\PTbox\Prony Toolbox Download\demos.html
But the results of the amplitudes are not consistant with the original signals.Can anyone tell me why? And there is no angle information from the PT Analysis.

I have a question regarding how I can extract each residue as a row or a colum versus time in the workspace. I tried with exportresults but I cannot figure out how it works.

i tried to use the prony analysis to isolate the different components of a shortcircuit current, but it seems that whenever any two components with of same frequency but one of them is decaying one the analysis dont offer the right output even the measured and prony out matches

I am using this software for eigenvalue analysis. I compared the values given by this software and Power System Toolbox are totally different. plz send link for documentation. Jiwan(IIT Delhi)

Thanks a lot.It is a excellent toolbox for a person like me who want to use prony method,but know little about the method.But in the fold,there is no help file tell me how to begin use this toolbox.
