AutoCorrelation PtByPt (Not in Base Package)

Computes the autocorrelation of the set of input data x.

initialize, when TRUE, initializes the internal state of the VI.
input data x is the set of input data.
sample length x is the length of each set of incoming data. The VI performs computation for each set of data. The default is 100. sample length must be greater than zero.
Rxx is the result of autocorrelation.
error returns any error or warning condition from the VI. Refer to Point By Point Error Codes for more information about these conditions.
