Parameters

NM  Int32

must be set to the row dimension of two-dimensional array parameters as declared in the calling program dimension statement.

N  Int32

is the order of the matrix.

LOW  Int32

and igh are integers determined by the balancing subroutine cbal. if cbal has not been used, set low=1, igh=n.

IGH  Int32

 

HR  Double

and hi contain the real and imaginary parts, respectively, of the complex upper hessenberg matrix. their lower triangles below the subdiagonal contain information about the unitary transformations used in the reduction by corth, if performed.

offset_hr  Int32

 

HI  Double

 

offset_hi  Int32

 

WR  Double

and wi contain the real and imaginary parts, respectively, of the eigenvalues. if an error exit is made, the eigenvalues should be correct for indices ierr+1,...,n.

offset_wr  Int32

 

WI  Double

 

offset_wi  Int32

 

IERR  Int32

is set to zero for normal return, j if the limit of 30*n iterations is exhausted while the j-th eigenvalue is being sought.
