where the dimension of the array x has been extended from the original n to

n + 2

. The output values x are stored in a different order with real and imaginary parts stored contiguously. The mapping of output elements is as follows:

$x [2 \times i - 1] \leftarrow x [i - 1]$ , for $i = 0, 1, \dots, n / 2$ and
$x [2 \times i] \leftarrow x [n - i - 1]$ , for $i = 1, 2, \dots, (n + 1) / 2$ .

$x [2 \times i] \leftarrow x [n - i - 1]$ , for $i = 1, 2, \dots, (n - 1) / 2$ .

If you were only using nag_complex_cholesky (f01bnc) in order to feed its results into nag_hermitian_lin_eqn_mult_rhs (f04awc), then the simple replacement function given further below, in the section for nag_hermitian_lin_eqn_mult_rhs (f04awc), will suffice. A more thorough replacement function is given here and it will put the same values in arrays a and p as nag_complex_cholesky (f01bnc) did.

Withdrawn at Mark 25.
Replaced by nag_dgeqrf (f08aec).

The subdiagonal elements of a and the elements of zeta returned by nag_dgeqrf (f08aec) are not the same as those returned by nag_real_qr (f01qcc). Subsequent calls to nag_real_apply_q (f01qdc) or nag_real_form_q (f01qec) must also be replaced by calls to nag_dorgqr (f08afc) or nag_dormqr (f08agc) as shown below.

Replaced by nag_dormqr (f08agc).

The following replacement is valid only if the previous call to nag_real_qr (f01qcc) has been replaced by a call to nag_dgeqrf (f08aec) as shown below. It also assumes that the second argument of nag_real_apply_q (f01qdc) is set to

Replaced by nag_zgeqrf (f08asc).

The subdiagonal elements of a and the elements of theta returned by nag_zgeqrf (f08asc) are not the same as those returned by nag_complex_qr (f01rcc). Subsequent calls to nag_complex_apply_q (f01rdc) or nag_complex_form_q (f01rec) must also be replaced by calls to nag_zunmqr (f08auc) or nag_zungqr (f08atc) as shown below.

Withdrawn at Mark 26.
Replaced by nag_dsygv (f08sac).

Note that the call to nag_dsygv (f08sac) will overwrite the upper triangles of the arrays a and b and leave the subdiagonal elements unchanged, whereas the call to nag_real_symm_general_eigenvalues (f02adc) overwrites the lower triangle and leaves the elements above the diagonal unchanged.

The call to nag_dtr_copy (f16qec) copies a to v, so a is left unchanged. If nag_real_symm_general_eigensystem (f02aec) was called with the same array supplied for v and a, then the call to nag_dtr_copy (f16qec) may be omitted.

Replaced by nag_dpotrf (f07fdc) and nag_det_real_sym (f03bfc).

nag_dpotrf (f07fdc) performs the Cholesky factorization and nag_det_real_sym (f03bfc) calculates the determinant from the factored form.

Note: subsequent solution of linear systems using the Cholesky factorization performed by nag_dpotrf (f07fdc) should be performed using nag_dpotrs (f07fec)).

Withdrawn at Mark 25.
Replaced by nag_zgetrf (f07arc) and nag_det_complex_gen (f03bnc).

nag_zgetrf (f07arc) performs the

L U

factorization and nag_det_complex_gen (f03bnc) calculates the determinant from the factored form.

Note: the details of the

L U

factorization performed by nag_zgetrf (f07arc) differ from those perfomed by nag_complex_lu (f03ahc); subsequent solution of linear systems using the

L U

factorization performed by nag_zgetrf (f07arc) should be performed using nag_zgetrs (f07asc). The determinant returned by nag_det_complex_gen (f03bnc) independently scales the real and imaginary parts whereas the determinant returned by nag_complex_lu (f03ahc) used a single scaling factor.

The factorization and solution of a positive definite linear system can be handled by calls to functions from Chapter f04.

The functions in Chapter f16 provide greater functionality than their corresponding functions in Chapter f06. The essential differences are:

The order argument. This provides the flexibility to operate on matrix data stored in row or column major order.
The addition of the fail argument to trap data errors. The f06 functions used to abort noisily.
The enumeration types and members use NAG_ as the prefix. This is to guard against accidental use of non-NAG enums.
Scale factors have been introduced in some functions. For example nag_dtrmv (f16pfc) has an extra argument, alpha which was not present in the corresponding old_dtrmv (f06pfc) function.

Replaced by nag_rand_basic (g05sac).

The Integer array state in the call to nag_rand_basic (g05sac) contains information on the base generator being used. This array must have been initialized prior to calling nag_rand_basic (g05sac) with a call to either nag_rand_init_repeatable (g05kfc) or nag_rand_init_nonrepeatable (g05kgc). The required length of the array state will depend on the base generator chosen during initialization.

Replaced by nag_rand_init_repeatable (g05kfc).

The Integer array state in the call to nag_rand_init_repeatable (g05kfc) contains information on the base generator being used. The base generator is chosen via the integer arguments genid and subid. The required length of the array state depends on the base generator chosen.

The first element of the state array contains the number of elements that are used by the random number generating functions, therefore either this number of elements can be copied, or the whole array (as defined in the calling program).

Replaced by nag_rand_gen_discrete (g05tdc).

There is no direct replacement function for nag_return_discrete (g05eyc).

nag_return_discrete (g05eyc) is designed to generate random draws from a distribution defined by a reference vector. These reference vectors are created by other functions in Chapter g05, for example nag_ref_vec_poisson (g05ecc), which have themselves been superseded. In order to replace a call to nag_return_discrete (g05eyc) you must identify which NAG function generated the reference vector being used and look up its replacement. For example, to replace a call to nag_return_discrete (g05eyc) preceded by a call to nag_ref_vec_discrete_pdf_cdf (g05exc), as in:

     /* nag_ref_vec_discrete_pdf_cdf (g05exc) */
     nag_ref_vec_discrete_pdf_cdf(p,np,sizep,distf,&r,&fail);
     /* nag_return_discrete (g05eyc) */
     x = nag_return_discrete(r);

you would need to look at the replacement function for nag_ref_vec_discrete_pdf_cdf (g05exc).
