    Computes the autocorrelation matrix of the input sequence x. Wire data to the x input to determine the instance to use.

    x

    The input sequence.

    datatype_icon

    order

    Order of the autocorrelation matrix. If the order is smaller than zero, this node returns an error.

    Default: 0

    datatype_icon

    method

    Method used to compute the autocorrelation matrix.

    0 0 AutoCorrelation (default)
    1 1 Pre-Windowed
    2 2 Post-Windowed
    3 3 Covariance
    4 4 Modified Covariance

    initial?

    Initialization of the internal buffer. The first time this node runs or if initial? is TRUE, LabVIEW initializes the internal buffer to empty. If initial? is FALSE, LabVIEW initializes the internal buffer to the final data points from the previous call to this instance. To process a large data sequence that consists of smaller blocks, set this input to TRUE for the first block and to FALSE for continuous processing of all remaining blocks.

    Default: FALSE

    datatype_icon

    autocorrelation matrix

    Autocorrelation matrix of x of the size of (order+1) multiplied by (order+1).

    datatype_icon

    error

    A value that represents any error or warning that occurs when this node executes.
