what will this code will perform ? Numclass=[]; for i = 1:nclass Classes=data.y(find(data.y==i)); if size(Classes) ~=0 Numclass = [Numclass; Classes(1)]; end end

Numclass=[];%empty vector array for i = 1:nclass Classes=data.y(find(data.y==i));%Find indices and values of nonzero elements if size(Classes) ~=0 Numclass = [Numclass; Classes(1)]; end end

clc ; clear all ;
Numclass=[]; % assigning a vairable, to append data later
for i = 1:nclass % nclass will be a number
Classes=data.y(find(data.y==i)); % data is a structure, from this data.y for i ispicked
if size(Classes) ~=0 % is Classes is not zero, append it to Numclass
Numclass = [Numclass; Classes(1)];
end
end
From where you are getting this? You must have some idea on what you are doing. If it is a existing code, this is not the way to understand.
