# Tricomi Function (G Dataflow)

Version:

Computes the Tricomi, or associated confluent hypergeometric, function.

## x

The input argument.

Default: 0

## a

The first parameter of the Tricomi function.

## b

The second parameter of the Tricomi function.

## error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error

## U(x, a, b)

Value of the Tricomi function.

## error out

Error information. The node produces this output according to standard error behavior.

## Algorithm for Computing the Tricomi Function

The Tricomi function U(x, a, b) is a solution of the following differential equation:

$x\frac{{d}^{2}w}{d{x}^{2}}+\left(b-x\right)\frac{dw}{dx}-aw=0$

Where This Node Can Run:

Desktop OS: Windows
