SYNOPSIS
subroutine qhsg(x,y,fdy,sdy,z,ndim)
PURPOSE
Compute vector of integral values for given general table of argument,
function, first derivative, and second derivative values.
USAGE
call qhsg (X,Y,FDY,SDY,Z,NDIM)
DESCRIPTION OF PARAMETERS
|
X |
- The input vector of argument values.
|
|
Y |
- The input vector of function values.
|
|
FDY |
- The input vector of first derivative.
|
|
SDY |
- The input vector of second derivative.
|
|
Z |
- The resulting vector of integral values. Z may be
identical with X,Y,FDY or SDY.
|
|
NDIM |
- The dimension of vectors X,Y,FDY,SDY,Z.
|
|
REMARKS
No action in case NDIM less than 1.
SUBROUTINES AND FUNCTION SUBPROGRAMS REQUIRED
None
METHOD
Beginning with Z(1)=0, evaluation of vector Z is done by
means of Hermitean sixth order integration formula.
