};

Description

The method is of fourth order and has five stages. It is described HERE. This method can be used with multiprecision types since the coefficients are defined analytically.

ToDo: add reference to paper.

Template Parameters

```
typename Coor
```
The type representing the coordinates q.
```
typename Momentum = Coor
```
The type representing the coordinates p.
```
typename Value = double
```
The basic value type. Should be something like float, double or a high-precision type.
```
typename CoorDeriv = Coor
```
The type representing the time derivative of the coordinate dq/dt.
```
typename MomentumDeriv = Coor
```
```
typename Time = Value
```
The type representing the time t.

typename Algebra = typename algebra_dispatcher< Coor >::algebra_type

The algebra.

typename Operations = typename operations_dispatcher< Coor >::operations_type

The operations.

```
typename Resizer = initially_resizer
```
The resizer policy.

`symplectic_rkn_sb3a_m4_mclachlan` public construct/copy/destruct

```
symplectic_rkn_sb3a_m4_mclachlan(const algebra_type & algebra = algebra_type());
```
Constructs the symplectic_rkn_sb3a_m4_mclachlan. This constructor can be used as a default constructor if the algebra has a default constructor.

Parameters:

algebra

A copy of algebra is made and stored inside explicit_stepper_base.
