# odeset

Specify ordinary differential equation options.

## Syntax

options = odeset('option1', value1, 'option2', value2)

## Inputs

`optionN`- The name of option N to set.
`valueN`- The value to set for option N.

## Outputs

- options
- A struct containing the options

## Examples

`options = odeset('RelTol', 1.0e-3, 'AbsTol', 1.0e-6)`

```
options = struct [
AbsTol: 1e-06
RelTol: 0.001
]
```

`options = odeset('Jacobian', @JacFunc)`

```
options = struct [
Jacobian: JacFunc
]
```

## Comments

The default value for RelTol is 1.0e-3. It is a scalar.

The default value for AbsTol is 1.0e-6. It can be specified as either a scalar that applies to every equation in the system, or as a vector with one element for each equation.

The default value for MaxStep is Inf.
