if else statement problems

I want to create a new data based on this rules:

1) if x = 0 AND y value within 52-336, then value of z will be 0. the value of Z will be 1 if y is less than 52 or more than 336.

2) if x = 1 AND y value within 38-176, then value of z will be 0. the value of Z will be 1 if y is less than 38 or more than 176.

This is my code:

x = [0,0,0,0,1,0,1,0,0,1];
y = [60,264,400,89,170,119,30,60,167,180];

for i = 10 
  if x (:,i) == 0 && y (:,i) >=52 && y (:,i) <=336            
    z (:,i) = 0;
  elseif x (:,i) == 0 && y (:,i) <52
    z(:,i) = 1;
  elseif x (:,i) == 0 && y (:,i) >336
    z(:,i) = 1;
  elseif x (:,i) == 1 && y (:,i) >=38 && y (:,i) <=176            
    z (:,i) = 0;
  else
    z(:,i) = 1;  
  end
end

i'm expecting z value will like this [0,0,1,0,0,0,1,0,0,1] but instead i got this value [0,0,0,0,0,0,0,0,0,1]

Can somebody help me to identify what is wrong with this code.

Thank You

The problem is very simple: your code only loops over one value:

for i = 10

Whereas you probably wanted to loop over ten values:

for i = 1:10

Here is a much simpler solution:

>> x = [0,0,0,0,1,0,1,0,0,1];
>> y = [60,264,400,89,170,119,30,60,167,180];
>> z = (x==0 & (y<52 | y>336)) | (x==1 & (y<38 | y>176))
z =
  0  0  1  0  0  0  1  0  0  1
