Write a Function called Is_decreasing that has the output variables yes_no?
显示 更早的评论
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

>> 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.
