MATLAB: Creating a matrix using diag

creating matrixdiagmatrix arraymatrix manipulation

Hi,

Would you please help me to write a script with "diag" command to create the matrix as shown in image. http://s1.postimage.org/5i4gd1esv/matrix.jpg By they way, it's a 99 X 99 matrix.

Thank you, John

>> z=zeros(3,1); z(1)=2; z(2)=-1; A=toeplitz(z)
A =
       2    -1     0
      -1     2    -1
       0    -1     2

MATLAB: Hello how to create this matrix with specific diagonals

Use toeplitz:

>> n = 5;
>> toeplitz([2,-1,zeros(1,n-2)])
ans =
   2  -1   0   0   0
  -1   2  -1   0   0
   0  -1   2  -1   0
   0   0  -1   2  -1
   0   0   0  -1   2
