This is very petty and you can ignore it, but most of the community would appreciate the extra half second to type out 'please' haha. Good luck!

A grouping variable must have the same number of observations (rows) as the table, data set array, or numeric array you are grouping. (Read here )
Assuming you have 24 data points in 2D space (i.e. with two features each) and 24 labels of which 12 are 1's and 12 are -1's.
labels = [ones(12,1);-ones(12,1)];
Hope this helps.
