removing repeats from lists
显示 更早的评论
Hi, I'm struggling to figure out an output list 'd' which has all elements that are in both lists 'a' and 'b', but not in list 'c' using below:
a=[3 5 1 8]
b=[1 5 2]
c=[5 1 4 2]
d=[ ]
but this code only works when removing 'b' from 'a' to make list 'c'.
a=[3 5 1 8];
b=[1 5 2]
n=length(a); m=length(b); c=[ ];
for j=1:n
flag = 0;
k=0;
while flag == 0 && k
k=k+1;
if a(j) == b(k)
flag = 1;
end;
end;
if flag == 0
c=[c a(j)];
end;
end;
c

Not many elements:
a = [3,5,1,8];
b = [1,5,2];
c = [5,1,4,2];
d = setdiff(intersect(a,b),c)

d=intersect(a,b);
d=d(~ismember(d,c));
