--- 171,181 ----
  ** Doing the frobenius normalization proved successfull in avoiding the
  ** the creating of NaN eigenvalues when the coefficients of the matrix
! ** were really large (> 50000).  Also, when the matrix norm was really
! ** small, the comparison to "epsilon" in ell_cubic mistook three seperate
! ** roots for a single and a double, with this matrix in particular:
! **  1.7421892  0.0137642  0.0152975
! **  0.0137642  1.7565432 -0.0062296
! **  0.0152975 -0.0062296  1.7700019
! ** (actually, this is prior to tenEigensolve's isotropic removal)
