Hello,
I created a predictive model with the classification learner but I can't actually see the predictions. What do I need to do in order to see them and how can I export them to excel?
Thanks

On the Classification Learner app, there is "export model" button.
After you have the model exported to your workspace, you can use
yhat = model.predictFcn(x)
where x is your input or test data.
If you want to write the variable yhat to csv, use csvwrite() or any similar function.

I get this now:
>> [yhat, yscores] = predict(trainedModel, table2array(gggggggggggg))
Error using table2array (line 37)
Unable to concatenate the specified table variables.
Caused by:
Error using categorical/cat (line 119)
Unable to concatenate a string array and a categorical array.
