uprod [Action][List][Calculation][prod]

Function: Returns the product of the elements in a list.

Syntax: prod (List-1[, List-2] [ ) ]

(List-1: Data, List-2: Freq)

Example: To determine the product of the elements in the list {1, 2, 3}

ucuml [Action][List][Calculation][cuml]

Function: Returns the cumulative sums of the elements in a list.

Syntax: cuml (List [ ) ]

Example: To determine the cumulative sums of the elements in the list {1, 2, 3}

uAlist [Action][List][Calculation][Alist]

Function: Returns a list whose elements are the differences between two adjacent elements in another list.

Syntax: Alist (List [ ) ]

Example: To generate a list whose elements are the differences between two adjacent elements in the list {1, 2, 4}

upercent [Action][List][Calculation][percent]

Function: Returns the percentage of each element in a list, the sum of which is assumed to be 100.

Syntax: percent (List [ ) ]

Example: To determine the percentage of each element in the list {1, 2, 3}

upolyEval [Action][List][Calculation][polyEval]

Function: Returns a polynomial arranged in the descending order of powers, so coefficients correspond sequentially to each element in the input list.

Syntax: polyEval (List [,Exp/List] [ ) ]

• “x” is the default when you omit “[,Exp/List]”.

Example: To create a second degree polynomial with the coefficients {1, 2, 3}

usequence [Action][List][Calculation][sequence]

Function: Returns the lowest-degree polynomial that represents the sequence expressed by the input list. When there are two lists, this command returns a polynomial that maps each element in the first list to its corresponding element in the second list.

Syntax: sequence (List-1[, List-2] [,variable] [ ) ]

• “x” is the default when you omit “[,variable]”.

Example: To determine a polynomial for a sequence expressed by the list {3, 5, 7, 9}

usumSeq [Action][List][Calculation][sumSeq]

Function: Finds the lowest-degree polynomial that represents the sequence expressed by the input list and returns the sum of the polynomial. When there are two lists, this command returns a polynomial that maps each element in the first list to its corresponding element in the second list, and returns the sum of the polynomial.
