# Create Orthogonal Polynomial (G Dataflow)

Creates orthogonal polynomial coefficients.

## type

Type of orthogonal polynomial coefficients to create.

Name Description
Chebyshev I Creates Chebyshev I polynomial coefficients.
Chebyshev II Creates Chebyshev II polynomial coefficients.
Legendre Creates Legendre polynomial coefficients.
Laguerre Creates Laguerre polynomial coefficients.
Hermite Creates Hermite polynomial coefficients.
Associate Laguerre Creates Associate Laguerre polynomial coefficients.
Gegenbauer Creates Gegenbauer polynomial coefficients.

Default: Chebyshev I

## alpha

Alpha value for creating the associate Laguerre and Gegenbauer polynomial coefficients.

When type is Gegenbauer, alpha must be a nonzero value.

Default: 0

## order

Order of the orthogonal polynomial coefficients.

If order is less than zero, the node sets polynomial to an empty array and returns an error.

Default: 0

## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

## polynomial

Orthogonal polynomial coefficients in ascending order of power.

## error out

Error information.

The node produces this output according to standard error behavior.
