what will this code will perform ? Numclass=[]; for i = 1:nclass Classes=da​ta.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.

My teacher has given me this code, she has told me to understand it well.As i am new to MATLAB, not able to understand whole well.So, asking for online help.
