## 1Purpose

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 Library function d02qwc. This allocated memory is used by functions d02qfc and d02qzc.

## 2Specification

 #include
The function may be called by the names: d02qyc, nag_ode_ivp_adams_rootdiag or nag_ode_ivp_adams_free.

## 3Description

The NAG Library functions d02qwc, d02qfc and 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; d02qyc may be used to free this memory when all calls to the functions d02qwc, d02qfc and d02qzc have been completed. A call to d02qyc may also be made prior to re-entering d02qwc with the argument ${\mathbf{state}}=\mathrm{Nag_NewStart}$.

None.

## 5Arguments

1: $\mathbf{opt}$Nag_ODE_Adams * Input/Output
On entry: the structure used in calls to the functions d02qwc, d02qfc and d02qzc.
On exit: all memory allocated to this structure will have been freed and the pointers set to NULL.

None.

Not applicable.

## 8Parallelism and Performance

d02qyc is not threaded in any implementation.
