NAME CPBDI - CPBDI computes the determinant of a complex Hermitian positive definite band matrix using the factors computed by CPBCO or CPBFA. If the inverse is needed, use CPBSL N times. SYNOPSYS SUBROUTINE CPBDI(ABD,LDA,N,M,DET) DESCRIPTION On Entry ABD COMPLEX(LDA, N) the output from CPBCO or CPBFA. LDA INTEGER the leading dimension of the array ABD . N INTEGER the order of the matrix A . M INTEGER the number of diagonals above the main diagonal. On Return DET REAL(2) determinant of original matrix in the form determinant = DET(1) * 10.0**DET(2) with 1.0 .LE. DET(1) .LT. 10.0 or DET(1) .EQ. 0.0 . LINPACK. This version dated 08/14/78 .
