Hi Chan,

I tried the code again with Matlab 2008a and it works fine for me. Your error simply means that in the function 'trainpso.m' the variable 'net' can not be found or read. This will happen if a call to 'clear net' or 'clear all' was made.

I advise you to train using the original code again and becareful when making modifications.

Good luck!

Thanks for informing me of this error. I will work on this and get back to you asap.

Hi Krystian,

Thank you for the question. Yes it seems to be a small compatibility issue. By now have you fixed this? If not I will work on fixing it asap and get back to you.

Hi Manish,

You get this error because you need to download the PSO toolbox and set the path in MATLAB. This is explained in the README file in this add-in, however for your convenience here is what you need to do to fix this error:
1. Download the PSO toolbox at http://www.mathworks.com/matlabcentral/fileexchange/28291-particle-swarm-optimization-research-toolbox.

2. Unzip the downloaded file.

3. On the MATLAB interface go to file -> set path -> add with subfolders. Then find the location of the unzipped downloaded file. -> Save

By following these steps MATLAB should recognise the Control_panel function.

Lte me know if this helps.

Good day users,

A PSO toolbox which can be used for NN trainig, and works with the latests versions of MATLAB, is now available on MathWorks.

The PSO toolbox is found at:
http://www.mathworks.com/matlabcentral/fileexchange/28291-particle-swarm-optimization-research-toolbox

The NN add-in for this PSO toolbox is found at: http://www.mathworks.com/matlabcentral/fileexchange/29565-neural-network-add-in-for-psort

Hi everyone, I also am using this toolbox but get the same error as most of you. I am using Matlab version 2013b. Tricia, could you please assist. Error is as follows:
Error using ==> trainpso at 54
Unrecognized code.
Error in ==> network.subsasgn>setTrainFcn at 2016
net.trainParam = feval(trainFcn,'defaultParam');
Error in ==> network.subsasgn>network_subsasgn at 462
if isempty(err), [net,err]=setTrainFcn(net,trainFcn); end
Error in ==> network.subsasgn at 11
net = network_subsasgn(net,subscripts,v,netname);
Error in ==> NN_training_demo at 20
net.trainFcn = 'trainpso'; %set the NN training function to use a PSO approach.
The name 'trainpso' is used for consistency with previous research (B. Birge,
2005

Hi every body,
I am using Nueral Network add-in for PSORT. it works very well when it trains networks with RegPSO algorithm (George Evers) for the NN_train_demo.m. But when i apply it for my problem, the error of output is quit high (the same input variables for ANNs training by BP algorithms is 1.81% but ANNs training by PSO(RegPSO) is more than 20% not acceptable).
any suggestions, please help

regards,
Narin

A good Toolbox for Matlab 7, I upgraded it to Matlab 8, let me know if you are interested.
Thanks

Hello Tricia
I'd like to test out your addin but i get the following error in Matlab 2012a
??? Error using ==> trainpso at 54

How to fix this error?

Hi
am using NN_training_demo nad getting the same problem with psotrain it seems unidentifed by NN toolbox. i run it on matlab 2012a. my PSO toolbox was obtained from the same link provided above by Tricia. please help
