Shuffles the elements in an array.

connector_pane_image
datatype_icon

input array

The input array to riffle.

This input supports the following data types:

  • 1D array of double-precision, floating-point numbers
  • 1D array of complex double-precision, floating-point numbers
  • 1D array of 32-bit, signed integer numbers
datatype_icon

seed

Seed value at which to riffle the input array.

Default: -1

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

riffled array

The input array with riffled elements.

datatype_icon

riffled indices

Corresponding index in the input array for each element in the riffled array.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

How This Node Riffles an Array

This node riffles the input array by randomly selecting two elements in the input array, swapping those elements, and then repeating this process n times, where n is the length of the input array.

Where This Node Can Run:

Desktop OS: Windows

FPGA: This product does not support FPGA devices

Web Server: Not supported in VIs that run in a web application
