while trying to run this code an error occurs due to the first line (Happy ) and it says that
Index in position 1 exceeds array bounds.
Happy = [trainf(1,:);trainf(3,:);trainf(5,:);trainf(6,:);trainf(15,:);trainf(16,:)];
Surprise = [trainf(2,:);trainf(4,:);trainf(7,:);trainf(8,:);trainf(17,:);trainf(18,:)];
Sad = [trainf(9,:);trainf(10,:);trainf(11,:);trainf(12,:);trainf(19,:)];
Anger = [trainf(13,:);trainf(14,:);trainf(20,:)];

trainf =
[]

Well then there you go. You can't extract rows that don't exist.

Hi Maryam,
As the trainf is an empty matrix i.e trainf=[], and you are trying to refer to the rows of an empty matrix, the code is throwing an error. Try by initializing the trainf matrix with the data and the code may work.
