Write a Function called Is_decreasing that has the output variables yes_no?

This Function should accept a row or column vector and determine whether or not the vector is decreasing. It should set yes_no=1 if the vector is decreasing and yes_no=0 if its not. This is what I have.

function [ yes_no ] = Is_decreasing( x )

k=2

while x(k-1)<x(k)

    k=k+1;

    yes_no=1

end end

Learn to write neat, simple and efficient MATALB code by writing vectorized code:

>> is_decreasing = @(v) all(diff(v)<0);
>> is_decreasing([3,2,1])
ans =  1
>> is_decreasing([1,2,3])
ans =  0

Loops are for low-level languages.
