How to get the elements that are different in two set without using the setdiff function in matlbab?

Answer 1

Here is the code to find the elements that are different in two sets by using for loops:

%define two arrays
a1 = [1,5,2,7,8];
a2 = [5,4,9,1,3,11,7];
diff = []; %initialize an array for diff
%go over the first array
for i=1:length(a1)
%check if element present in second array
if ~ismember(a1(i), a2)
%add to diff is not present
diff = [diff a1(i)];
end
end

%now go over the second array
for i=1:length(a2)
%check if element present in first array
if ~ismember(a2(i), a1)
%add to diff is not present
diff = [diff a2(i)];
end
end

%print the answer
diff
