- ProdSeries
- Computes the series of incremental products associated with a given sequence of numerical values.
- Usage
- ProdSeries(array)
- Arguments
- array (ARRAY(T)). T is either INT or REAL. If the argument is Undef, returns Undef
- Returned Object
- If array has type ARRAY(T), the function returns an element of type ARRAY(T), with the same number of elements. If the argument is Undef, returns Undef
- Description
- Returns the mathematical series associated with the sequence of numerical values defined in array. Let array=
 , then the result is the array whose ith element is defined by  . If array contains Undef elements, these elements are considered as having value 1 (they do not affect the overall product of other elements).
