How to compare values of two vectors?

Hello everyone, how can I compare values between 2 vectors? Let me explain, for example I have two vectors:

vec1= [10 20 30 40 50]% transmission

vec2= [10 20 30 40 50 60 70]; % reception

It should show me the following result:

for example 10,20,30,40,50 was transmitted but 10,20,30,40,50,60,70 were received, then the result would be 5 values were sent but 7 values were received, which would be the value 60 and 70.

Any help would be very helpful, thanks in advance.

One option could be the setdiff function, another could be ismember —

vec1= [10 20 30 40 50]; % transmission
vec2= [10 20 30 40 50 60 70]; % reception
difference = setdiff(vec2,vec1)                     % Use 'setdiff'

difference = 1×2

60 70

differenceidx = ~ismember(vec2,vec1)                % Use 'ismember' And Negate The Result

differenceidx = 1×7 logical array
   0   0   0   0   0   1   1

difference = vec2(differenceidx)

difference = 1×2

60 70

Note the order, so that the longer vector would be the first argument and the shorter vector the second argument.
