Newton divide and difference

I was provided with a set of data point and was told to write up a matlab code for Newton divide and difference method of interpolation.

Y = [0 9 15 39 49 57 69 74 81 91 100];
t = [8000 7000 6000 5000 4000 3000 2000 1000 900 800 700];

I have look into a few of the example based on divide and difference interpolation and found a few thats similar but it does not quite work for me.

Can anyone guide me on this?

What code did you try, and what error did you encounter? Do you have a sample input and output you can use for your code to compare ?
