finding an element that meet the conditions in a vector

I have a vector that looks like this

A = [1 2 3 1 2 3 1 2 3]

and I would like to write a function that returns True if there is a number between 5 to 9 or False if not

An alternative solution uses ismember:

any(ismember(5:9,A))

It checks if any of the elements in 5:9 is present in A. If you leave out the any, it will tell you which of the elements is present in A:

>> ismember([1,5,9],A)
ans =
   1   0   0

(indicating that 1 is present, but 5 and 9 are not).

As suggested by etmuse, you can just use any with two conditions.

function output = findelem(A)
    if(any(A>5 & A<9))
        output = true;
        return;
    end
    output = false;
end

Call function:

>>findelem([1 2 3 1 2 3 1 2 3]) 

returns logical 0

>>findelem([1 2 3 1 6 3 1 2 3])

returns logical 1

As @beaker correctly points out, you can simply use:

function output = findelem(A)
    output = (any(A>5 & A<9))
end
