of the array. The results will be a running aerage of a spatial average on the
various source array's elements.
Randomize
Initializes the random‐number generator.
Syntax
Randomize(source)
RND
Generates a random number.
Syntax
RND(source)
A.6.10.1 Histograms
Histogram
Processes input data as either a standard histogram (frequency distribution) or a
weighted‐value histogram.
Syntax
Histogram(BinSelect, DataType, DisableVar, Bins, Form, WtVal,
LoLim, UpLim)
Histogram4D
Processes input data as either a standard histogram (frequency distribution) or a
weighted‐value histogram of up to four dimensions.
Syntax
Histogram4D(BinSelect, Source, DataType, DisableVar, Bins1,
Bins2, Bins3, Bins4, Form, WtVal, LoLim1, UpLim1, LoLim2,
UpLim2, LoLim3, UpLim3, LoLim4, UpLim4)
LevelCrossing
Processes data into a one‐ or two‐dimensional histogram using a level‐crossing
counting algorithm.
Syntax

2ndDim, CrossingArray, 2ndArray, Hysteresis, Option)
RainFlow
Processes data with the Rainflow counting algorithm, essential to estimating
cumulative damage fatigue to components undergoing stress / strain cycles (see
