@kirma That worked. How do I accept your answer?

@J.M.'stechnicaldifficulties But whether or not there are infinite spacings of 2 or 4 or 220 are unknown.

Is it impossible to evenly space an arbitrary set? I'm just messing around; visualizing how many divisors there are around certain primes.

I'm using ctr+Enter and ctr+, to make a matrix within Mathematica, and passing the values that way. I haven't seen the link you sent, thank you for the info.

@J.M., Actually, with some more experimenting (and more Diffeq homework), Carl Woll's answer doesn't work for the matrix {{4, 5},{-2, 6}} with the eigenvector{{1 - 3:ii:},{2}}. It doesn't seem to work with any vector with complex eigenvectors

@J.M. For whatever reason, I had trouble with it a week ago, but not today. Even with the same matrices. I'll delete this post in a bit.
