# PDL::GSLSF::AIRY(3pm)

PDL interface to GSL Special Functions

## NAME

PDL::GSLSF::AIRY - PDL interface to GSL Special Functions

## DESCRIPTION

This is an interface to the Special Function package present in the GNU Scientific Library.

## FUNCTIONS

### gsl\_sf\_airy\_Ai

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Airy Function Ai(x).

gsl\_sf\_airy\_Ai does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

### gsl\_sf\_airy\_Bi

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Airy Function Bi(x).

gsl\_sf\_airy\_Bi does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

### gsl\_sf\_airy\_Ai\_scaled

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Scaled Airy Function Ai(x). Ai(x) for x \< 0  and exp(+2/3 x^{3/2}) Ai(x) for  x \> 0.

gsl\_sf\_airy\_Ai\_scaled does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

### gsl\_sf\_airy\_Bi\_scaled

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Scaled Airy Function Bi(x). Bi(x) for x \< 0  and exp(+2/3 x^{3/2}) Bi(x) for  x \> 0.

gsl\_sf\_airy\_Bi\_scaled does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

### gsl\_sf\_airy\_Ai\_deriv

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Derivative Airy Function Ai\`(x).

gsl\_sf\_airy\_Ai\_deriv does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

### gsl\_sf\_airy\_Bi\_deriv

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Derivative Airy Function Bi\`(x).

gsl\_sf\_airy\_Bi\_deriv does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

### gsl\_sf\_airy\_Ai\_deriv\_scaled

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Derivative Scaled Airy Function Ai(x). Ai\`(x) for x \< 0  and exp(+2/3 x^{3/2}) Ai\`(x) for  x \> 0.

gsl\_sf\_airy\_Ai\_deriv\_scaled does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.

### gsl\_sf\_airy\_Bi\_deriv\_scaled

```
  Signature: (double x(); double [o]y(); double [o]e())
```

Derivative Scaled Airy Function Bi(x). Bi\`(x) for x \< 0  and exp(+2/3 x^{3/2}) Bi\`(x) for  x \> 0.

gsl\_sf\_airy\_Bi\_deriv\_scaled does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.
