Answer 1

Instead of

f=x.*y

shouldn't it be

 f=x.*w

I can't see how you get any output at all, whether correct or incorrect. You should be getting an error message.

anyway thx matt

@ricardo: The error would have been obvious, when you read the error message. The description "I get WA(wrong answer" is cryptic.

Please run this code on your computer and examine the error messages. Using the debugger is a good idea also. But letting the forum solve your Cody challenges is not a resource friendly method for this game.

Answer 2

[VELDANDI THARUN]

function y = weighted_average(x,w)

y =(x*w.')/length(x)

end
