jobz |
Control for if vectors/values/both are returned. |
range |
Parameter to determine the search criteria for eigenvalues. |
n |
Problem size. |
a |
Matrix. |
desca |
ScaLAPACK descriptor array. |
vl, vu |
Endpoints of the interval subset of the real line in which to search for eigenvalues, if specified by |
il, iu |
Eigenvalues with indices |
abstol |
Absolute error tolerance for the eigenvalues. |
orfac |
Eigenvectors with eigenvalues below orfac*norm(a) of each other are reorthogonalized. |
