A student of mine saved a .mat file containing variables named x1, x2, ..., x50, y1, y2, etc. How can I write program that will open the .mat file, and loop through each of these pairs of data. Somehow it involves "who" but I'm not seeing how to make it work.

X = load('StudentsMatfile.mat') ;
LABELS = fieldnames(X) ;
N = numel(LABELS)
DATA = cell(N,1)
for k=1:N
DATA{k} = X.(LABELS{k}) ;
end
save ('SupervisorMatfile.mat', 'DATA','LABELS') ;
