BOOTSTRAP (klibm) functions


LIBRARY ROUTINE

klin_dgedi - computes the determinate and inverse of a matrix

LIBRARY CALL

int klin_dgedi(
   double *matrix,
   int    rows,
   int    cols,
   int   *pivot,
   int    job,
   double *work,
   double *det)

INPUT

OUTPUT

RETURN VALUE

TRUE (1) all the time

DESCRIPTION

This routine will compute the determinant and inverse of an NxN matrix using the factors computed by klin_sgeco or klin_dgefa.

The determinant functionality is not well tested.

ADDITIONAL INFORMATION

none

EXAMPLES

none

SIDE EFFECTS

none

RESTRICTIONS

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 klin_sgeco has set rcond > 0.0 or dgefa has set info < 0.

MODIFICATION

none
