Unique Numbers and Multiplicity (G Dataflow)

Last Modified: January 12, 2018

Obtains all the unique numbers from the input array and determines the multiplicity of each unique number.

connector_pane_image
datatype_icon

numbers

Array of numbers.

This input accepts the following data types:

  • 1D array of double-precision, floating-point numbers
  • 1D array of complex double-precision, floating-point numbers
datatype_icon

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

datatype_icon

unique numbers

All the unique numbers in numbers. The nth element of unique numbers has multiplicity given by the nth element of multiplicity.

This output can return the following data types:

  • 1D array of double-precision, floating-point numbers
  • 1D array of complex double-precision, floating-point numbers
datatype_icon

multiplicity

Number of times each unique number in numbers occurs. The nth element of multiplicity corresponds to the nth element of unique numbers.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

The following table lists examples of inputs and outputs of this node.
