I want to find a Data set file used in an example in MathWorks website

The data set name is

BufferedHumanActivity.mat

and the example name is

Human Activity Recognition Using Signal Feature Extraction and Machine Learning.

Thanks.

[Muhammad Kashan]

load BufferedHumanActivity.mat

How can we load above dataset in Online Matlab?

Follow the instructions in the accepted answer, but use the 'Open in MATLAB Online' option instead of 'Copy Command'.

Beginning in R2023a, the product documentation is no longer installed by default (see here). You may have noticed when you installed R2023a that when it completed, you had a notification that the documenation had not been installed. The side effect of this is that some example datasets are no longer included with the product install.

This means some example datasets are no longer available by default. You can still access them by either installing the documentation, or by finding an example in the online documentation that uses that file, and then use the 'Open in MATLAB Online' or 'Copy Command' workflows to open that example (along with any associated data files) in your MATLAB instance.

Here a link to the example that uses bufferedhumanactivity.mat

• Human Activity Recognition Using Signal Feature Extraction and Machine Learning

The copy command is openExample('signal/HumanActivityRecognitionUsingMobilePhoneDataExample')

In Windows, the file(s) will be downloaded to your C:\Users\<user>\Documents\MATLAB\Examples\<ver>\ folder.

If it is a file you use often, consider adding the example folder to your MATLAB Path.

Thanks for the Replay.

I have 2021a version, no such example are in the Examples Folder, I used the code to open and searched Manually as well. Did not find it.

Regarding the offline documentaions, its 9 GB. not sure if I need all that.

[Cris LaPierre]

Not in R2021a. An example using this dataset was not introduced until R2021b.

You will need to install at least that version of MATLAB to access it, along with the Signal Processing Toolbox.

Or, if you have access to MATLAB Online, you can try the worflow I suggested there.

[Mohammad]

is it possible for you to attach the file or the script here so I can use it?

I cant install a new version of MATLAB for just one file.

I would Appreciate it if you do

Thanks

Please see if you can access it in MATLAB Online,
