spinblk

Purpose

determine the spin tensors for a group of vectors

Synopsis

S = spinblk(u)

Description

SPINBLK determine the spin tensors for a group of vectors 
  S = SPINBLK (U)
  the function determines the spin tensors for a group of vectors in U;
  U must have size N=3K where K is the number of vectors
  the array S contains the spin tensors in K vertically concatenated 3x3 blocks
