numpy.linalg.eig returns column vectors #8

Closed PetMetz closed 1 year ago

PetMetz commented 1 year ago

Eigenvectors returned by np.linalg.eig are column vectors.

In the first edition, slicing was determined according to properties discussed by Ting, so they may incidentally be correctly handled.

I think I've beat this to death-- the structure of the eigen vector matrix shows up in Ting's textbook and in a 1988 paper where he defines the matrix U =[[A,\bar{A}], [B, \bar{B}]] which corresponds with a row matrix of eigen vectors grouped by their conjugate pairs.

The previous slicing of \xi and the reordering of \xi into U result in equivalent construction of the (3,3) matrices A, B.
