Comparing different sized arrays in Matlab

I need to compare two different arrays in Matlab. It's going to be used for a Yahtzee game. If I have an array that contains [1 2 3 4] and an array that contains [1 2 3 4 5], how do I check if the first array is contained within the second array. I just need to know a T/F result, not anything about which elements are missing, etc.

another option, 

all(intersect(x,y)==x)

but ismember is probably more efficient....

ismember will do it. For example:

x = [1 2 3 4]
y = [1 2 3 4 5]
all(ismember(x,y))

You can also use setdiff. For example:

isempty(setdiff(x,y))
