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.

Hi all,

I just simply changed line 24 in pronytoolbar.m as below:

mlabel = 1;%get(h1(j)),xlate('TooltipString'));

After that it runs normally.

Have fun

I think the 'xlate' function translates from another language and may no longer be supported by MATLAB. Since 'TooltipString' is already in English, I simply removed the xlate function and its parentheses. It seems to work afterwards.

How could i use this useful Tool? I got the same problem that the other people have mentioned before

Hi

I got the same error.

pronytool
Undefined function or variable 'xlate'.

Error in pronytoolbar (line 24)
mlabel = get(h1(j),xlate('TooltipString'));

Error in pronyanalysistool>pronyanalysistool_OpeningFcn (line 62)
pronytoolbar(hObject,'on');

Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in pronyanalysistool (line 42)

Thank you

Hi,
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)
evalin('base','mmv2struct(vars)');

Error in gui_mainfcn (line 96)
feval(varargin{:});

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

Error while evaluating uicontrol Callback

Undefined function 'pronyanalysistool' for input arguments of type
'struct'.

Thanks for sharing,,,,

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

Thanks

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.

Hi,

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.

Thanks

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

Very usefull toolbox! thanks to creators and holy god of atheism...

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 very usefull for industry people.
But I have problem finding document to explain how I can use this toolbox.

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.
