SGEDI - SGEDI computes the determinant and inverse of a matrix using
the factors computed by SGECO or SGEFA.
A REAL(LDA, N)
the output from SGECO or SGEFA.
the leading dimension of the array A .
the order of the matrix A .
the pivot vector from SGECO or SGEFA.
work vector. Contents destroyed.
= 11 both determinant and inverse.
= 01 inverse only.
= 10 determinant only. On Return
A inverse of original matrix if requested.
determinant of original matrix if requested.
Otherwise not referenced.
Determinant = DET(1) * 10.0**DET(2)
with 1.0 .LE. ABS(DET(1)) .LT. 10.0
or DET(1) .EQ. 0.0 . Error Condition
A division by zero will occur if the input factor contains a zero on the
diagonal and the inverse is requested. It will not occur if the
subroutines are called correctly and if SGECO has set RCOND .GT. 0.0 or
SGEFA has set INFO .EQ. 0 . LINPACK. This version dated 08/14/78 .
