## 示例

`pd = makedist('InverseGaussian')`
```pd = InverseGaussianDistribution Inverse Gaussian distribution mu = 1 lambda = 1 ```

`pd = makedist('InverseGaussian','mu',2,'lambda',4)`
```pd = InverseGaussianDistribution Inverse Gaussian distribution mu = 2 lambda = 4 ```

`s = std(pd)`
```s = 1.4142 ```
