How do I find the lowest values in one array that are greater than each value from another array?

I've got two arrays, for example:

x=[5 16 27]';
y=[1 3 7 8 9 10 12 13 15 17 21 24 28 31 54]';

I want to create a variable z that returns the lowest values in y that are greater than each of the values in x. In this example z should return 7, 17, and 28.

I've tried a comnbination of min and > but can't make it work.

Thanks!

Hello Liam,

Can you try if the following code helps with the problem you have?

z=zeros(1,0); %defining an array z to store output in
for i=1:3 %depends on size of array x
    t=y(y>x(i)); %this will store all elements in t that are greater than x(i)
    z(end+1)=t(1); %this will extract the first element of t which is also the smallest (since y was in ascending order)
end
