If you have any more questions, then attach your data (your training table of predictors) and code to read it in with the paperclip icon after you read this:
You could try to have your response be a single double vector, or cell array of strings if that is allowed.

That should be no problem as long as you have one response for each of the 500+ sets of data. If the response variable is in var4 of a table, and the data is in columns after that you can do (t is your table):
% Extract response (ground truth) from column called var4
responseVector = t.var4;
% Get measurement data from columns 5 and to the right.
tPredictors = t(:, 5:end); % This is a subtable gotten from table "t".
