comment Why do the eigenvectors for two similar matrixes differ by a large amount
Thanks for the answer, indeed a Hermit matrix can always be decomposed into its spectrum form $H=\sum_n \lambda_n \left|n\right\rangle \left\langle n \right|$, and comparing the spectrum is a good way to compare the original matrix. But I am actually interested in calculating the eigenvectors of a parametric matrix which changes slightly in a range and found that this behavior of Eigensystem. I'm wondering what costs this seems random behavior? Does Eigensystem use LAPACK under the hood?

comment Is there something like DensityPlot3D to visualize atomic orbitals?
That's fantastic! Indeed RegionPlot3D is much faster. And it also solves the problem of holes in ContourPlot3D.

comment Is Mathematica `ContourPlot` function really so efficient?
@Szabolcs where is the source code of this package located at? I looked up the folder AddOns-Packages-Experimental but the folder only contains a PacletInfo.m file.
