Unable to find file or directory 'fisheriris.net'

I'm doing a project but I'm unable to load fisheriris.net. I can't find an installation link for the file anywhere either, and when looking through my toolbox there wasn't any file by the name 'stats' for me. Any way I can resolve this issue. I'm a beginner in MatLab and this has really stumped me. I'm using the R2002b version.

fisheriris.net may be something that was created when someone was doing neural network manipulation of the built-in (with the Statistics and Machine Learning Toolbox) fisheriris.mat or fisheriris.csv file.

>> which('fisheriris.mat')

C:\Program Files\MATLAB\R2022b\toolbox\stats\statsdemos\fisheriris.mat

>> which('fisheriris.csv')

C:\Program Files\MATLAB\R2022b\toolbox\stats\statsdemos\fisheriris.csv

Do you have the stats toolbox? Type "ver" in the command window to check.

Checked there's no fisheriris file and machine learning toolbox... but I've downloaded the machine learning toolbox through adds on...What should I do?

I find fisheriris.mat and fisheriris.csv going back to at least R2015b. However, I do not see any reference to fisheriris.net anywhere other on the internet other than your question. What leads you to expect that fisheriris.net should exist ?

Since I'm using the R2002b version of MatLab, I don't have the stats folder under the toolbox file. Perhaps I'd need to install an older version of MatLab in order to have it.

As for fisheriris.net, I was able to find one page where I was able to download the dataset and load it. I've provided the link below and it seems to be working fine so far.

It seems to be the accurate dataset my teacher wanted, so I'm just continuing with it since there's not much I can work with at the moment anyways. Thanks for your answer though! I may install an older version of MatLab if possible too.

@Banuji

Releases were not designated by year until 2006; there was no R2002b.

The link you give is for fisheriris.mat -- not fisheriris.net .

fisheriris.mat is present in R2022b if you have the Statistics and Machine Learning Toolbox installed; it is at

filename = fullfile(matlabroot, 'toolbox', 'stats', 'statsdemos', 'fisheriris.mat')

filename = '/MATLAB/toolbox/stats/statsdemos/fisheriris.mat'

ls(filename)

/MATLAB/toolbox/stats/statsdemos/fisheriris.mat

@Banuji: the page you link to only has FISHERIRIS.MAT (which is already included in the statistics toolbox), not FISHERIRIS.NET (which is what you asked about in your question, and what you incorrectly wrote in your comment).

For the record, please tell us where you found FISHERIRIS.NET.

"I don't have the stats folder under the toolbox file. Perhaps I'd need to install an older version of MatLab in order to have it."

In order to get the Statistics and Machine Learning toolbox you would need to install the Statistics and Machine Learning toolbox (and have a valid licence for it).
