Creates a data queue of real numbers.

Note By default, reentrant execution is enabled in all Point By Point VIs.

Inputs/Outputs

  • cbool.png initialize —

    initialize, when TRUE, initializes the internal state of the VI.

  • cdbl.png input data point —

    input data point is an input data point.

  • ci32.png sample length —

    sample length is the length of each set of incoming data. The VI processes each set of data. The default is 100. sample length must be greater than zero.

  • cdbl.png initial queue element —

    initial queue element specifies the initial element value in the data queues.

  • idbl.png eliminated element —

    eliminated element is the first point eliminated from the queue.

  • i1ddbl.png Current Queue —

    Current Queue is the new array created by eliminating the first point and appending the new point.

  • i1ddbl.png Previous Queue —

    Previous Queue is the set of data before any operation in this call.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

  • ii32.png current length —

    current length is the size of the current queue.

    • The data queue begins as a set defined by the initial queue element that matches the size of sample length.
