Issue loading classifier created with a previous version of Matlab

Hi all,

In an old version of Matlab, I trained a convolutional neuronal network that generated a classifier file "class2.mat"

I recently updated Matlab (R2023b) but when I try to load the classifier, I get the following message:

load('class2.mat')

Warning: Variable 'classifier' originially saved as a classreg.learning.classif.CompactClassificationECOC cannot be instantiated as an object and will be read as a uint32

Is there anything I can do to update the classifier so I don't have to re-train the CNN again?

You do not have the Statistics and Machine Learning toolbox installed and licensed on the new system.
