What is the significance/geometric interpretation of eigen values or eigen vectors in a vector space?

  • We like to reduce transformations to combinations of simpler ones. A very simple kind of transformation is a dilation. We can often reduce a linear transformation to dilations to different extents along different directions. This is called diagonalization (strictly speaking, diagonalization over the real numbers). With a bit more work, we can also make eigenvalues tell us about rotation. What they cannot really tell us about is shear. – Ian Nov 04 '15 at 05:05
  • There is definitely an old question about this somewhere on the site with plenty of good answers. – Ben Grossmann Nov 04 '15 at 05:20
