I want to know how to assing variable value depending on the value it self. Explained in detail below.

Consider I=[2,3,5];

now depending on the values of I i want to assign other variables as

r2=2, r3=3, r5=5.

If the elements in I are huge, how do I assign the index in the variable r in a simple for loop ??

"now depending on the values of I i want to assign other variables as r2=2, r3=3, r5=5."

That is not a good approach to writing code. Read this to know why:

It would be much simpler and more efficient to just use indexing.

[Stephen23]

This is MATLAB, so just keep it simple:

>> x = [2,3,5];
>> r = zeros(1,max(x));
>> r(x) = x
r =
   0   2   3   0   5

Dear Sir,

Why do you want to assign a variable (I) to a different variable (r)? I(i) itself is will do the work.

Try this:

for i=1:length(I)%if I is either row vector or column vector
    r(i)=I(i);
end

According to you, I will get r(3)=5. That doesn't meet my requirement.
