Array.indices()

These functions operate on array locations and values to create contours and other interesting operations.

Array.indices(Function,SubtractByArray,ScaleByArray,DoNotShowIndices,RowArray)

Returns the result of applying the Function/FunctionSet to each x,y location of the array, then subtracts and scales the results with SubtractByArray and ScaleByArray. DoNotShowIndices suppresses the x,y indices when outputting the result.
