i have 4 matrices i want to call each matrix to get divided by 2
which is something like this
for i=1: 4
y(i)= x(i)/2
end
but this for loop is is not working beacuse location of x1,x2,x3,x4 is not fixed.

Use indexing.
Indexing is neat, simple to debug, and very effiicient (unlike what you are trying to do).

Why not make a cell array?
x{1}= A([1,2,3,5,8],:);
x{2}= A([1,2,3,4,8],:);
x{3}=A([1,2,3,5,7],:);
x{4}=A([1,2,3,4,5,8],:);
for i=1:4
y{i}=x{i}/2;
end
