These functions operate on array locations and values to create contours and other interesting operations. Array Indices and XY Functions
Array.xy(Function, OffsetArray, ScaleArray,GiveIndicesAlso,DoCentering)
Returns the result of applying the Function/FunctionSet to each x,y location of the array, then offsets (adds) and scales the results with OffsetArray [default 0] and ScaleArray [default 1]. GiveIndicesAlso [default false] gives the x,y indices when outputting the result.
DoCentering is by default false [note: DoCentering is advanced option and is undocumented, need detail checking of behavior when this parameter is true].
