DRIVER | PROBLEM SOLVED |
dndrv1 | Standard eigenvalue problem (bmat = 'I') |
in the regular mode (iparam(7) = 1) No shift is | |
needed in this driver. | |
dndrv2 | Standard eigenvalue problem (bmat = 'I') |
in a shift-invert mode (iparam(7) = 3) The shift is | |
real (sigmai = 0.0). | |
dndrv3 | Generalized eigenvalue problem (bmat = 'G') |
in the regular inverse mode (iparam(7) = 2) No shift | |
is needed in this driver. | |
dndrv4 | Generalized eigenvalue problem (bmat = 'G') |
in a shift-invert mode (iparam(7) = 3) with | |
a real shift (sigmai = 0.0). | |
dndrv5 | Generalized eigenvalue problem (bmat = 'G') |
in a shift invert mode (iparam(7) = 3) The shift | |
has a nonzero imaginary part (sigmai 0.) | |
dndrv6 | Solve a generalized eigenvalue problem (bmat = 'G') |
in a shift invert mode (iparam(7) = 4) The shift | |
has a nonzero imaginary part (sigmai 0). |
