Creating a function with a logical output.

Hi all,
I am quite confused. I have a function say like this:
function [output] = TLU( inputs, weights, threshold )
activationMagnitude = sum(weights.*inputs)
if activationMagnitude > threshold
output = true;
else
output = false;
end
But when I use class(ans) it always shows a char data type - despite me specifying the output as either true or false!
Why is this?
Best regards,
Craig

There's nothing wrong with your function, you can just do it more concisely
function output = TLU( inputs, weights, threshold )
output = sum(weights.*inputs) > threshold;
Then
y = TLU([1 2 3], [ 4 5 6 ], 100)
yields
y =
0
And
class(y)
yields
ans =
logical
But of course then class(ans) gives char (because ans is the string 'logical'), but this has nothing to do with the class returned by your function.

It does return logical for me.
What does
class(TLU(rand, rand, rand))
return? If ans returns something different, you may have overwritten its value before you call to class()

The question is what ans represent?
