unique to within a constant factor?
we always listen to the phrase in quantum mechanics textbook that says this eigenvector is unique to within a constant factor.
What does it actually mean?
unique means there is one and only one??
constant factor: a constant 2 or 3 or... maybe??
I don't really catch the physical picture of it, I just hope for some mathematical examples that can illustrate this. Thank you
