How to find relation between two set?

I have two set of variable:

i=1

c=[1 2 3 4 5 6]

Now How can I find that i is in the c or i is the part of c?

I also want to make decision on that if i is in the c.

[Sanket Raval]

i=1;

c=[1 2 3 4 5 6];

M=ismember(c,i);

N=any(M)

I found this solution.

Your suggestions are welcome.

Try ismember():

i=3;
c=[1 2 3 4 5 6];
[ia1, ic1] = ismember(i, c)

ia1 = logical
   1

ic1 = 3

[ia2, ic2] = ismember(c, i)

ia2 = 1×6 logical array
   0   0   1   0   0   0

ic2 = 1×6

0 0 1 0 0 0

Use whichever form gives you the information you need or want.
