Hi Yeap,
Assuming that x is the element you want to check and a is the array, this function will not because you are comparing a 1x1 double with a 1xn double array. You need to compare each element of a with that of x.
Please look at the following code where I have used a FOR loop:
function Checking(x)
a=([1,3,5,8,9]);
for i = 1:length(a)
if x==a(i)
disp('It is an element')
else
disp('Not an element')
end
end

Note that will say it is Not an element once for each element of "a" that it does not equal.
