CGBDI(3F)							     CGBDI(3F)

NAME
     CGBDI   - CGBDI computes the determinant of a band matrix using the
     factors computed by CGBCO or CGBFA.  If the inverse is needed, use CGBSL
     N	times.

SYNOPSYS
      SUBROUTINE CGBDI(ABD,LDA,N,ML,MU,IPVT,DET)

DESCRIPTION
     On Entry

     ABD COMPLEX(LDA, N)
	the output from CGBCo or CGBFA.

     LDA INTEGER
	the leading dimension of the array  ABD .

     N INTEGER
	the order of the original matrix.

     ML INTEGER
	number of diagonals below the main diagonal.

     MU INTEGER
	number of diagonals above the main diagonal.

     IPVT INTEGER(N)
	the pivot vector from CGBCO or CGBFA.  On Return

     DET COMPLEX(2)
	determinant of original matrix.
	Determinant = DET(1) * 10.0**DET(2)
	with  1.0 .LE. CABS1(DET(1)) .LT. 10.0
	or  DET(1) = 0.0 .  LINPACK.  This version dated 08/14/78 .  Cleve
