g13byc allocates memory to the four pointers in the structure of type Nag_TransfOrder. The structure is used to hold the transfer function model orders of the input series for some functions in Chapter G13. This function must be called before any attempt is made to access this structure.

2 Specification

#include <nag.h>

void	g13byc (Integer nseries, Nag_TransfOrder transfv, NagError fail)

The function may be called by the names: g13byc or nag_tsa_transf_orders.

3 Description

The transfer function model orders of the input series are supplied to the time series function in memory allocated to four pointers. These pointers are the constituent members of the structure of type Nag_TransfOrder used by some functions in Chapter G13.

The purpose of g13byc is to allocate memory to these four pointers.

4 References

None.

5 Arguments

1: $nseries$ – Integer Input

On entry: the total number of input and output series. There may be any number of input series (including none), but always one output series. (See g13bec or g13bjc for details).

Constraint:

nseries \geq 1

2: $transfv$ – Nag_TransfOrder *

Pointer to structure of type Nag_TransfOrder with the following members:

b – Integer *Output
q – Integer *Output
p – Integer *
r – Integer *Output: On exit: each of the pointers will have been allocated sufficient memory. (See g13bec or g13bjc for details).

3: $fail$ – NagError * Input/Output
