Dear Support,

I have a question regarding different sizes of arrays. I have for example 2 arrays that looks like this:

x =[0, 1, 2, 1, 0];
y =[0, 0.5, 1, 1.5, 2, 1.5, 1, 0.5, 0];

I want to extend in this case the array of array x to fit the size of array y. The only condition that I have is that the boundaries of array x remains the same, and that array x is a palindrome.

Can you help me with this?

Thanks in advance!

Kind regards,

Emile Biever

Of course I am more interesting in a function on how to do this. You can see at first glance that you can make the arrays similar by placing 0.5, and 1.5 on both sides of array x.

x = [0, 1, 2, 1, 0];
y = [0, 0.5, 1, 1.5, 2, 1.5, 1, 0.5, 0];
xnew = interp1(x,linspace(1,numel(x),numel(y)))
xnew = 1×9
