Parameters

JOB  String

(input) CHARACTER*1 Specifies the type of backward transformation required: = 'N', do nothing, return immediately; = 'P', do backward transformation for permutation only; = 'S', do backward transformation for scaling only; = 'B', do backward transformations for both permutation and scaling. JOB must be the same as the argument JOB supplied to DGEBAL.

SIDE  String

(input) CHARACTER*1 = 'R': V contains right eigenvectors; = 'L': V contains left eigenvectors.

N  Int32

(input) INTEGER The number of rows of the matrix V. N .GE. 0.

ILO  Int32

(input) INTEGER

IHI  Int32

(input) INTEGER The integers ILO and IHI determined by DGEBAL. 1 .LE. ILO .LE. IHI .LE. N, if N .GT. 0; ILO=1 and IHI=0, if N=0.

SCALE  Double

(input) DOUBLE PRECISION array, dimension (N) Details of the permutation and scaling factors, as returned by DGEBAL.

offset_scale  Int32

 

M  Int32

(input) INTEGER The number of columns of the matrix V. M .GE. 0.

V  Double

(input/output) DOUBLE PRECISION array, dimension (LDV,M) On entry, the matrix of right or left eigenvectors to be transformed, as returned by DHSEIN or DTREVC. On exit, V is overwritten by the transformed eigenvectors.

offset_v  Int32

 

LDV  Int32

(input) INTEGER The leading dimension of the array V. LDV .GE. max(1,N).

INFO  Int32

(output) INTEGER = 0: successful exit .LT. 0: if INFO = -i, the i-th argument had an illegal value.
