Noise Generator (Gamma) (G Dataflow)

A Boolean that controls the reseeding of the noise sample generator after the first call of the node.

Default: False

Event number of the unit mean Poisson process.

order must be greater than 0.

Default: 1

Initial internal seed state of the noise generator.

This input must be passed from the state out output of another call to this node.

This node uses state in as the initial internal seed state of the noise generator if reset is True or if this is the first call of the node. If state in is unwired or contains invalid values, this nodes uses seed as the initial internal seed state of the noise generator.

x seed

Internal x seed. x seed must be greater than 0.

y seed

Internal y seed. y seed must be greater than 0.

z seed

Internal z seed. z seed must be greater than 0.

Number that this node uses to initialize the noise generator.

This node initializes the noise generator using seed when this node meets both of the following conditions:

• This is the first call of this node or reset is True.
• state in is unwired or contains invalid values.

Default: -1

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

Sample rate in samples per second.

This input is available only if you configure this node to return a waveform.

Default: 1000

Number of samples in the signal.

samples must be greater than 0. Otherwise, this node returns an error.

This input is available when you configure this node to return a waveform or an array of double-precision, floating-point numbers.

Default: 1000

Timestamp of the output signal. If this input is unwired, this node uses the current time as the timestamp of the output signal.

This input is available only if you configure this node to return a waveform.

Gamma-distributed, pseudorandom pattern.

This output can return the following data types:

• Waveform
• Double-precision, floating-point number
• 1D array of double-precision, floating-point numbers

Final internal seed state of the noise generator.

x seed

Internal x seed.

y seed

Internal y seed.

z seed

Internal z seed.

Error information.
