if condition equal many variables

If 6==6==6
c=1
Else
c=0
end

When i type the above code i get c=0 but logically i should get c=6 As 6 is equal to 6. Where is my error and how could i rewrite the code?

You should realize that "6==6==6" is operated on as:

   (6==6)==6

The (6==6) will give a true result, and which in combination with the third 6 will be converted to a numerical 1. Then you have 1==6 which is false. You will always get a false result with c = 0 as a result. In other words 6==6==6 is definitely false in the matlab world. Advice: don't use it! What were you trying to achieve?

So how do i rewrite it, assume u have x,y,z=6 and u want to see if x=y=z

if x == y && y == z
