MATLAB: I want to traverse an array in an ‘inverse s’ order and store in a single row array is there any matlab function or code for this?eg[1 2 3; 3 4 5; 4 5 1] becomes [1,2,3,5,4,3,4,5,1]

digital image processingmatrix manipulation

 [1 2 3; 3 4 5; 4 5 1]

becomes

 [1,2,3,5,4,3,4,5,1]

Best Answer

>> A = [1,2,3;3,4,5;4,5,1];
>> A(2:2:end,:) = A(2:2:end,end:-1:1);
>> reshape(A',1,[])
ans =
   1   2   3   5   4   3   4   5   1

for i=1:n-1
aa=a;
aa(i)=[];
for j=i+1:n
mm=[];
mm=[aa(1:j-1),a(i),aa(j:n-1)];
m(k,:)=mm;
