Hello,

I have found a paper describing an interesting method for protein sequence
analysis (CABIOS vol.6 no.2 1990 pp71-80), but couldn`t understand the
following:

transpose -of 1 or 2 dim. matrix
unitary vector
eigenvector

Anyone willing to explain these to a biologist, please?
If so, contact me by e-mail.

Fragments of the paper:

...Then the power spectrum Ps(v) of h may be written: [ ] where nt is the
transpose of n. ...

...where Ws(v) is a non-negative definite symmetrical matrix. Thus, the
unitary vector n0 which maximizes Ps(v) is the eigenvector of Ws(v)
associated with the largest eigenvalue l0(lambda zero).

Thanks,
