)

Arguments

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 range.
il, iu	Eigenvalues with indices il, ..., iu will be found, if specified by range.
abstol	Absolute error tolerance for the eigenvalues.
orfac	Eigenvectors with eigenvalues below orfac*norm(a) of each other are reorthogonalized.
