Beginning in R2023a, the product documentation is no longer installed by default (see here). 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.
For example, one data set that has been removed is ovariancancer.mat. I found that dataset used in 3 examples:
- Regularize Wide Data in Parallel
- Regularize Discriminant Analysis Classifier
- Select Features for Classifying High-Dimensional Data
The copy command from one of them is openExample('stats/RegularizeWideDatainParallelExample')
If it is a file you use often, consider adding the example folder to your MATLAB Path.
