I'm making a custom loop for training a neural network. When I was trying to use the "splitEachLabel" function for splitting the datastore, I got an error:
[imdsTrain, imdsVal] = splitEachLabel(imds,0.8,'randomize');
"Unrecognized function or variable 'splitEachLabel'."
I checked if I have toolboxes that are needed for the project and if this function exists .

>> which splitEachLabel -all
'splitEachLabel' not found.
I also run in command line:
run restoredefaultpath; rehash toolboxcache
because that was suggested by Copilot. That didn't help.

Ran in:
My guess is that you need the Audio Toolbox to use the function:
which splitEachLabel
/MATLAB/toolbox/audio/audio/@audioDatastore/splitEachLabel.m % audioDatastore method
[~, products] = matlab.codetools.requiredFilesAndProducts('splitEachLabel.m')
products = 1×2 struct array with fields:
Name Version ProductNumber Certain
products.Name
ans = 'MATLAB'
ans = 'Audio Toolbox'
