# NAG CL Interfaceg13xzc (free)

## 1Purpose

g13xzc frees the memory allocated by NAG functions to the options structure, type Nag_G13_Opt. This structure is used by some functions in Chapter G13.

## 2Specification

 #include
 void g13xzc (Nag_G13_Opt *options)
The function may be called by the names: g13xzc or nag_tsa_free.

## 3Description

The structure of type Nag_G13_Opt is used by some functions in Chapter G13. This structure is allocated memory by these functions during use.
g13xzc is supplied to allow you to easily free the allocated memory and set the associated pointers to NULL.
Use of g13xzc is not essential but is recommended if the calling program does not terminate shortly after calling the g13 time series functions and memory conservation is important.

None.

## 5Arguments

1: $\mathbf{options}$Nag_G13_Opt * Input/Output
On entry: the options structure, of type Nag_G13_Opt, used in a call to a NAG Time Series Analysis function.
On exit: the pointers with NAG allocated memory will have been freed and set to NULL.

None.

Not applicable.

## 8Parallelism and Performance

g13xzc is not threaded in any implementation.
