I have a matrix A = [1 1 0 0 1 1]

I have a matrix A = [1 1 0 0 1 1]. I want to add 0 one by one on this matrix like this

A = [0 1 1 0 0 1 1]

A= [1 0 1 0 0 1 1]

A = [1 1 0 0 0 1 1]

up to so on all the places. How I will do that via coding?

Answer 1

[KSSV]

A = [1 1 0 0 1 1] ;
m = length(A) ; 
B = zeros(m+1) ; 


insert = @(a, x, n)cat(2,  x(1:n), a, x(n+1:end));

for i = 1:m+1
  T = insert(0,A,i-1) ; 
 B(i,:) = T ;  
endfor

>> A = [1,1,0,0,1,1];
>> B = toeplitz([0,A])
B =
   0   1   1   0   0   1   1
   1   0   1   1   0   0   1
   1   1   0   1   1   0   0
   0   1   1   0   1   1   0
   0   0   1   1   0   1   1
   1   0   0   1   1   0   1
   1   1   0   0   1   1   0
