Relocate element from a row to another

Hello,i want to relocate an element from a row to an another and delete the other row.For example i have the matrix

A=[1 2 4 8 3 1;
   1 9 7 6 1  ;
   1 5 1     ]

and i want to relocate the 5 so i will have the matrix

A=[1 2 4 8 3 1;
   1 9 7 5 6 1]

Neither the beginning nor the ending A are legal; best you could do would be a cell array.

The "want" is also indeterminate...what's the logic for deciding what's the end result; without some rule best you can do is simply create it as desired.

It was a theoretical example not the problem I want to solve. The real matrixes would be at the start

    A=[1 2 4 8 3 1;
       1 9 7 6 1 0;
       1 5 1 0 0 0]

and the final

    A=[1 2 4 8 3 1;
       1 9 7 5 6 1],

I remove the last row which has only ones.

I don't get why the "5" ends up between the "7" and the "6".

Because he said so...

It's not possible to understand the rule you want to follow, from the one example you give.

[Giannakis Stoukas]

Actually it is a problem of local search algorithm,and it is too complicated it explain it from here. I just wanted the orders to move the element 5 between 7 and 6,and move all the other elements one position right.The rule to delete a row is "if the row has only zeros or ones,delete it",and i want the orders to do it.I know i am not very comprehensible,but it is a bit complicated to explain all the theory.

Answer 1

[the cyclist]

 A=[1 2 4 8 3 1;
    1 9 7 6 1 0;
    1 5 1 0 0 0]

 A = [A(1,:);
     A(2,1:3) A(3,2) A(2,4:5)]

This is my best guess at what you want.

Answer 2

Well, it's not possible to write anything except the specific answer without a definition of the logic. Anything else is indiscernible from magic, not science.

But, let's see, addressing the question as asked...

>> id76=sub2ind(size(A'),4,2);
>> id5=sub2ind(size(A'),2,3);
>> B=reshape(A',1,[]);
>> B=reshape([B(1:id76-1) B(id5) B(id76:id5-1) B(id5+1:end)],size(A,2),[]).';
>> B(all(B==0|B==1,2),:)=[]
B =
   1     2     4     8     3     1
   1     9     7     5     6     1
>>

Needless to say, to make this of much use in general you'll have to have rules to locate the magic numbers used to compute the indices id5 and id76
