Description2…")
A.2.3.1 Single-Source
Average
Stores the average value over the output interval for the source variable or each
element of the array specified.
Syntax
Average(Reps, Source, DataType, DisableVar)
Covariance
Calculates the covariance of values in an array over time.
Syntax
Covariance(NumVals, Source, DataType, DisableVar, NumCov)
FFT
Performs a Fast Fourier Transform on a time series of measurements stored in an
array.
Syntax
FFT(Source, DataType, N, Tau, Units, Option)
Maximum
Stores the maximum value over the output interval.
Syntax
Maximum(Reps, Source, DataType, DisableVar, Time)
Median
Stores the median of a dependant variable over the output interval.
Syntax
Median(Reps, Source, MaxN, DataType, DisableVar)
Minimum
Stores the minimum value over the output interval.
Syntax
Minimum(Reps, Source, DataType, DisableVar, Time)
Moment
Stores the mathematical moment of a value over the output interval.
Syntax
Moment(Reps, Source, Order, DataType, DisableVar)
