Origin 2017 NAG Changes

For example:

#include <OC_nag8.h>
#include <nag\OC_nag_ex.h>

has to be changed into:

#include <OC_nag.h>
//#include <nag\OC_nag_ex.h>//not need, only oc_nag.h required.

If there is an error as below after compiling, it might be caused by the NAG function that have been withdrawn since the new release NAG C Library.

Referring to the following table Withdrawn Functions, the replacement function can be found and used instead. For example:

• e01sac has been replaced by e01sjc since Mark 23.

  Origin C: Example: Interpolation and Gridding: XYZ Gridding by Renka Cline Method

  e01sac(method, nSize, vx, vy, vz, &comm, &optional, &fail);

  can be changed instead of:

  Origin C: Example: Interpolation and Gridding: XYZ Gridding by Renka Cline Method

  //The arguments triang and grads that were not included in e01sac should be declared before calling the function e01sjc
  e01sjc(nSize, vx, vy, vz, triang, grads, &fail); 

• e01sbc has been replaced by e01skc since Mark 23.

  Origin C: Example: Interpolation and Gridding: XYZ Gridding by Renka Cline Method

  e01sbc(&comm, nRows*nCols, vxGrid, vyGrid, mat, &fail);

  can be changed instead of:

  Origin C: Example: Interpolation and Gridding: XYZ Gridding by Renka Cline Method

  //The arguments triang and grads that were not included in e01sbc should be declared before calling the function e01skc
  //More details of e01skc can be referred to NGA C Library
  for(int ii=0; ii < nRows; ii++)
  {
  	for(int jj=0; jj < nCols; jj++)
  	{
  		e01skc(nSize,vx, vy, vz, triang, grads, vxGrid[jj], vyGrid[ii], &mat[jj][ii], &fail);
      }
  }

• d01ajc has been replaced by d01sjc since Mark 24.

  Origin C: Example: Quadrature Integral: Simple Integral Function

  d01ajc(func, a, b, epsabs, epsrel, max_num_subint, &result, &abserr, &qp, &fail);

  can be changed instead of:

  Origin C: Example: Quadrature Integral: Simple Integral Function

  d01sjc(func, a, b, epsabs, epsrel, max_num_subint,&result, &abserr, &qp, &comm, &fail);

  The examples usually indicate the minimum change necessary, but many of the replacement functions have additional flexibility. You are recommended to familiarize yourself with the replacement NAG function in NAG C Library.

If there is no replacement required of the withdrawn function, it can be removed from the code file. For example:

• e01szc has been withdrawn since Mark 23.

  Origin C: Example: Interpolation and Gridding: XYZ Gridding by Renka Cline Method

  if (fail.code != NE_NOERROR)
  {
  	printf("Error from e01sac: %s\n", fail.message);
  	//nag_2d_scat_free
  	e01szc(&comm);
  	return fail.code;
  }

  has to be changed into:

  Origin C: Example: Interpolation and Gridding: XYZ Gridding by Renka Cline Method

  if (fail.code != NE_NOERROR)
  {
  	printf("Error from e01sac: %s\n", fail.message);
  	return fail.code;
  }

There are 551 new user-callable functions included in the NAG C Library of Origin 2017, which can be referred to the table New Functions as follow.
