Math is a hobby for me. I've been reading up on Eigenvectors and Eigenvalues. It get the manipulations involved, but can't imagine the applications -- and the books I have don't help. Can people provide a few examples? Specific examples, if possible -- not just, they are used in electronics, or physics, or whatever, but rather, something like: M is the matrix which describes such-and-such physical property or transformation or process, its eigenvectors V correspond to such and such property, and the eigenvalues of V and M indicate such-and-such. Thanks in advance for all replies. Steve O. Standard Antiflame Disclaimer: Please don't flame me. I may actually *be* an idiot, but even idiots have feelings.
