# NAG C Library Function Document

## 1Purpose

nag_tsa_free (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 #include
 void nag_tsa_free (Nag_G13_Opt *options)

## 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.
nag_tsa_free (g13xzc) is supplied to allow you to easily free the allocated memory and set the associated pointers to NULL.
Use of nag_tsa_free (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

nag_tsa_free (g13xzc) is not threaded in any implementation.
