Assigning names to values in vector

I would like to keep track on my vectors and need to assign a name to each entry.

For example: xN=[2 1]=[x1 x2], or something like it.

Is it possible to assign the values a handle of some sort? I'm switch the values around, and I don't know beforehand were the going to end up.

So the name should not interfere with the algebraic operations

I assume this is only one step in a larger project. If you describe that larger project (why are you "switch [sic] the values around"?) we may be able to offer an alternative way to solve the problem, either by doing this tracking or avoiding the need to track.

Basically I am switching bases in a matrix (simplex method), so I need to keep track on the vectors. In the end I must also update the values that I resive

No, it is not possible to assign a handle to a value. Use symbolic variable names and subs() as needed. For example,

x = sym('x', [1 5]);
y = sum(x.^(0:4));
xvals = randi([-9 9], 1, 4);

subs(y, x, xvals)

xvals2 = xvals(randperm(length(xvals)));
subs(y, x, xvals2)

Not working. Is their no way to solve this issue without sym?

[Walter Roberson]

Of course there are ways. I already linked you to an explanation of why most of those ways are not good mechanisms to use.

Tried to make sense of what you linked me, but I'm a total noob and can't figure out a solution
