# Math::GSL::Spline(3pm)

Splines

## NAME

Math::GSL::Spline - Splines

## SYNOPSIS

```
    use Math::GSL::Spline qw/:all/;
```

## DESCRIPTION

The functions described in the Interp module required the user to supply pointers to the x and y arrays on each call. The following functions are equivalent to the corresponding gsl\_interp functions but maintain a copy of this data in the gsl\_spline object. This removes the need to pass both xa and ya as arguments on each evaluation.

- •

  `"gsl_spline_alloc($T, $size)"`

- •

  `"gsl_spline_init($spline, $xa, $ya, $size)"`

- •

  `gsl_spline_free($spline)`

- •

  `gsl_spline_name($spline)`

- •

  `gsl_spline_min_size($spline)`

- •

  `"gsl_spline_eval_e($spline, $x, $acc)"`

- •

  `"gsl_spline_eval($spline, $x, $acc)"`

- •

  `"gsl_spline_eval_deriv_e($spline, $x, $acc)"`

- •

  `"gsl_spline_eval_deriv($spline, $x, $acc)"`

- •

  `"gsl_spline_eval_deriv2_e($spline, $x, $acc)"`

- •

  `"gsl_spline_eval_deriv2($spline, $x, $acc)"`

- •

  `"gsl_spline_eval_integ_e($spline, $a, $b, $acc)"`

- •

  `"gsl_spline_eval_integ($spline, $a, $b, $acc)"`

For more information on the functions, we refer you to the GSL official documentation: \<http://www.gnu.org/software/gsl/manual/html\_node/\>
