HI, everyone. I found myself stack in this problem:
Suppose that you determine the masses of 100 objects by weighing the first, then weighing the first and second together, and then weighing the rest in triplets: the first, second, and third; the second, third, and fourth; and so forth.
The problem asked me to identify the model parameters and the data ( g= Gm).
I did so on my copybook, but I want to write a matlab script for this and I am struggling about how to write the G matrix in the correct way in matlab.
This is how I write G on my copybook:
[1 0 0 0 0....0]
[1 1 0 0 .....0]
[1 1 1 .......0]
[0 1 1 1 ....0]
[...................]
[0 0 0 0 ...1]
Can anyone help me?
Thank for all who will answer.

n=whatever size matrix you want.
G=eye(n)+diag(ones(1,n-1),-1)+diag(ones(1,n-2),-2);
