NAME¶
/home/abuild/rpmbuild/BUILD/lapack-3.12.0/TESTING/EIG/dsxt1.f
SYNOPSIS¶
Functions/Subroutines¶
double precision function DSXT1 (ijob, d1, n1, d2, n2,
abstol, ulp, unfl)
DSXT1
Function/Subroutine Documentation¶
double precision function DSXT1 (integer ijob, double precision, dimension( * ) d1, integer n1, double precision, dimension( * ) d2, integer n2, double precision abstol, double precision ulp, double precision unfl)¶
DSXT1
Purpose:
!> !> DSXT1 computes the difference between a set of eigenvalues. !> The result is returned as the function value. !> !> IJOB = 1: Computes max { min | D1(i)-D2(j) | } !> i j !> !> IJOB = 2: Computes max { min | D1(i)-D2(j) | / !> i j !> ( ABSTOL + |D1(i)|*ULP ) } !>
Parameters
IJOB
!> IJOB is INTEGER !> Specifies the type of tests to be performed. (See above.) !>
D1
!> D1 is DOUBLE PRECISION array, dimension (N1) !> The first array. D1 should be in increasing order, i.e., !> D1(j) <= D1(j+1). !>
N1
!> N1 is INTEGER !> The length of D1. !>
D2
!> D2 is DOUBLE PRECISION array, dimension (N2) !> The second array. D2 should be in increasing order, i.e., !> D2(j) <= D2(j+1). !>
N2
!> N2 is INTEGER !> The length of D2. !>
ABSTOL
!> ABSTOL is DOUBLE PRECISION !> The absolute tolerance, used as a measure of the error. !>
ULP
!> ULP is DOUBLE PRECISION !> Machine precision. !>
UNFL
!> UNFL is DOUBLE PRECISION !> The smallest positive number whose reciprocal does not !> overflow. !>
