How to let 2 vector row to multiply by itself

hi I want vector m to multiply with n but for some reason I got this

input(4,7)

i =

4 5 6 7

output =

16 25 36 49

this is my code

function output=input(m,n)

i=m:n

output=i.*i

end

What exactly is the numeric output you desire? Your current code squares each element, which apparently is not what you wanted. Maybe you wanted output = i * n?

like I want it to be like 4x5x6x7 but i wasn't sure how to do it I tried m*i but it will be like (4x4) (4x5) (4x6) (4x7)

I tried to use if command inside the function command, but it won't let me do it. Can you tell me why ? pls maybe I can learn something from it

[Dai Nguyen]

if m<n

i=m:n

output=

else

i=n:m

output=

? Doesn’t prod() do what you want? Or your ”homework” requires a loop?

[Dai Nguyen]

my teacher doesn't require a loop at all, but I just wanna create a loop that can adapt to any inputs and still get the same answer.

Sorry I'm really new to matlab and I want to learn a lot from it.

Thank you for your time,

 m = 4;
 n = 7;
 prod(m : n)

Thank you. I haven't used prod before but this command is pretty awesome, is it stand for product? is there other command that serve the same purpose as prod ?
