MATLAB: Conversion of an Matrix

homework not originally tagged as homeworkmatrixmatrix conversion

I have an array : A = [0 3 5 7 8 9 1 3 4 0]. I want to convert it into 1×3 matrices such as [0 3 5], [3 5 7], [5 7 8]…[3 4 0] and so on.
My code is:
 clc
 A = [0 3 5 7 8 9 1 3 4 0];
 B = zeros(1, 3);
 r=1;
 c=3;
 for i = r:c
   for k = 1:3
      B(k) = A(i)
     r=r+1;
     c=c+1;
   end
 end
But it doesn't seem to be working correct. Can somebody help?

Use the hankel (link) function to create a Hankel matrix:
A = [0 3 5 7 8 9 1 3 4 0];
B = hankel(A,A(1:4:end))
B =
     0     3     5
     3     5     7
     5     7     8
     7     8     9
     8     9     1
     9     1     3
     1     3     4
     3     4     0
     4     0     8
     0     8     4
