If statement with two conditions

Hello everyone, once again.

Please I need a fix for this code, I get the same answer for each condition.

function out = select(condition, a, b)

if a > b == condition
    out = a;
else
    out = b;
end

How can I fix this?

explicitly state your inputs

The comments for your function don't make sense. What is int2 that keeps being referred to and what is the point of 'condition' and what is it? a logical? char? double? The code suggests it would be a logical though why you would do this is not at all understandable!

Oh, sorry bro, i've edited it, and removed the comment.

Yes, as Adam said, the comments don't make sense, and it's very unclear what you're trying to achieve. Your current code is exactly equivalent to:

if condition
    if a > b
        out = a;
    else
        out = b;
    end
else
    if ~(a > b)
        out = a;
    else
        out = b;
    end
end

assuming condition, a, and b are scalars (if they're vectors the whole logic is a lot more complicated). Whether or not, it's what you wanted to achieve is unknown.

I get the same answer for each condition

No, you will get a different result for condition = true than for condition = false (or 0 or 1), unless a and b are equal of course.

Note that if either of a, b or condition are vectors, then vector rules apply to if and yes, it's very likely the if is always false.

Thank you Guillaume, thank you all.
