# NAG Library Function Document

## 1Purpose

nag_ode_ivp_adams_free (d02qyc) is the function for freeing memory from the structure of type Nag_ODE_Adams. This memory will have been allocated to pointers within this structure during calls to the NAG C Library function nag_ode_ivp_adams_setup (d02qwc). This allocated memory is used by functions nag_ode_ivp_adams_roots (d02qfc) and nag_ode_ivp_adams_interp (d02qzc).

## 3Description

The NAG C Library functions nag_ode_ivp_adams_setup (d02qwc), nag_ode_ivp_adams_roots (d02qfc) and nag_ode_ivp_adams_interp (d02qzc) use a structure of type Nag_ODE_Adams to retain and communicate information between calls of these functions. During this process memory is allocated to several pointers within the structure; nag_ode_ivp_adams_free (d02qyc) may be used to free this memory when all calls to the functions nag_ode_ivp_adams_setup (d02qwc), nag_ode_ivp_adams_roots (d02qfc) and nag_ode_ivp_adams_interp (d02qzc) have been completed. A call to nag_ode_ivp_adams_free (d02qyc) may also be made prior to re-entering nag_ode_ivp_adams_setup (d02qwc) with the argument ${\mathbf{state}}=\mathrm{Nag_NewStart}$.

None.

## 5Arguments
