How can I form a square matrix in this form regardless of its dimension. Note that the pattern; 1 will form after three 0 from the centre.

在 MATLAB Online 中打开

k = 2; % define how often to repeat the pattern
result = toeplitz([5 repmat([1 0 0 0],1,k)])

gives:

result =
   1     0     0     0     1     0     0     0
   5     1     0     0     0     1     0     0
   1     5     1     0     0     0     1     0
   0     1     5     1     0     0     0     1
   0     0     1     5     1     0     0     0
   0     0     0     1     5     1     0     0
   1     0     0     0     1     5     1     0
   0     1     0     0     0     1     5     1
   0     0     1     0     0     0     1     5
