C***PURPOSE  Computes the determinant of a COMPLEX HERMITIAN POSITIVE
C            DEFINITE BAND matrix using factors from CPBCO or CPBFA.
C            Use CPBSL for inverse using the factors computed by CPBCO
C            or CPBFA.
C***DESCRIPTION
C
C     CPBDI computes the determinant
C     of a complex Hermitian positive definite band matrix
C     using the factors computed by CPBCO or CPBFA.
C     If the inverse is needed, use CPBSL  N  times.
