combining results into a single matrix

Code:

h = [1 2 3 4 5];

for i = 2:4

First_Matrix = [h(i-1) h(i) h(i+1) ]

end

Result:

First_Matrix =

1 2 3

First_Matrix =

2 3 4

First_Matrix =

3 4 5

I want help combining the result into a single matrix which is from 3x5 from h1 to h5, I want the answer to look like.

First_Matrix = [ 1 2 3 0 0; 0 2 3 4 0; 0 0 3 4 5]

and I don't want to hard code it. please help! I would really appreciate it if somone can help me.

One way.

h = [1 2 3 4 5];

n=numel(h);
m=n-2;

First_Matrix=toeplitz([1,zeros(1,m-1)]   ,[1 1 1 zeros(1,n-3)]).*h

First_Matrix = 3×5

1 2 3 0 0 0 2 3 4 0 0 0 3 4 5
