# NAG Library Function Document

## 1Purpose

nag_tsa_options_init (g13bxc) initializes the structure options. This structure is used by some functions in Chapter g13. This function must be called before any direct assignments are made to members of the options structure.

## 2Specification

 #include #include
 void nag_tsa_options_init (Nag_G13_Opt *options)

## 3Description

A number of optional parameters are applicable to several functions in Chapter g13. These arguments are set by means of a structure of type Nag_G13_Opt. This initialization function sets the members of the structure to null values indicating that the default values should be used for these arguments. If argument values other than the default values are required, they must be assigned to the appropriate members of the options structure in the calling program.
This assignment of optional parameters values to the options structure must be preceded by a call to nag_tsa_options_init (g13bxc).

None.

## 5Arguments

1:    $\mathbf{options}$Nag_G13_Opt *Output
On exit: the initialized option structure.

None.

Not applicable.

## 8Parallelism and Performance

nag_tsa_options_init (g13bxc) is not threaded in any implementation.
