The following functions find the maximum and minimum values of a
dataset (or their indices). If the data contains `NaN`

s then a
`NaN`

will be returned, since the maximum or minimum value is
undefined. For functions which return an index, the location of the
first `NaN`

in the array is returned.

- Function:
*double***gsl_stats_max***(const double*`data`[], size_t`stride`, size_t`n`) This function returns the maximum value in

`data`, a dataset of length`n`with stride`stride`. The maximum value is defined as the value of the element*x_i*which satisfies*x_i >= x_j*for all*j*.If you want instead to find the element with the largest absolute magnitude you will need to apply

`fabs`

or`abs`

to your data before calling this function.

- Function:
*double***gsl_stats_min***(const double*`data`[], size_t`stride`, size_t`n`) This function returns the minimum value in

`data`, a dataset of length`n`with stride`stride`. The minimum value is defined as the value of the element*x_i*which satisfies*x_i <= x_j*for all*j*.If you want instead to find the element with the smallest absolute magnitude you will need to apply

`fabs`

or`abs`

to your data before calling this function.

- Function:
*void***gsl_stats_minmax***(double **`min`, double *`max`, const double`data`[], size_t`stride`, size_t`n`) This function finds both the minimum and maximum values

`min`,`max`in`data`in a single pass.

- Function:
*size_t***gsl_stats_max_index***(const double*`data`[], size_t`stride`, size_t`n`) This function returns the index of the maximum value in

`data`, a dataset of length`n`with stride`stride`. The maximum value is defined as the value of the element*x_i*which satisfies*x_i >= x_j*for all*j*. When there are several equal maximum elements then the first one is chosen.

- Function:
*size_t***gsl_stats_min_index***(const double*`data`[], size_t`stride`, size_t`n`) This function returns the index of the minimum value in

`data`, a dataset of length`n`with stride`stride`. The minimum value is defined as the value of the element*x_i*which satisfies*x_i >= x_j*for all*j*. When there are several equal minimum elements then the first one is chosen.

- Function:
*void***gsl_stats_minmax_index***(size_t **`min_index`, size_t *`max_index`, const double`data`[], size_t`stride`, size_t`n`) This function returns the indexes

`min_index`,`max_index`of the minimum and maximum values in`data`in a single pass.
