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]

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

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.

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
