write this following matrix

4 views (last 30 days)
How can I write the following matrix
I define n=100
And I generate the following code
D= toeplitz ([0 1 zeros(1, n-2) -1]/ (2*h))
but I get wrong matrix. How can I correct it?

Actually, it can be done with this Zeynep.
c = [0 -1 zeros(1,n-3)];
r = [0 1 zeros(1,n-3)];
D = toeplitz(c,r) / (2*h)

Try this:
n = 100;
D = (diag(ones(n-1,1),1) - diag(ones(n-1,1),-1))/(2*h);
You can also use spdiags. or sparse, or many other tools. But diag as I did it above is about the simplest way.

Many thanks for your great help!! :) I use this matrix in this question my question is here. But I get an error message. Please can you take a look at it? (This is not assignment or something else like this. On these lockdown days, I try to learn matlab by myself, and I have no one to ask or to learn) Many thanks again.
