Class Sumproduct

  • All Implemented Interfaces:

    public final class Sumproduct
    extends java.lang.Object
    implements Function
    Implementation for the Excel function SUMPRODUCT

    Syntax :
    SUMPRODUCT ( array1[, array2[, array3[, ...]]])

    array1, ... arrayN  typically area references, possibly cell references or scalar values

    Let An(i,j) represent the element in the ith row jth column of the nth array
    Assuming each array has the same dimensions (W, H), the result is defined as:
    SUMPRODUCT = Σi: 1..H   (  Σj: 1..W   (  Πn: 1..N An(i,j)  )  )

                                  int srcCellRow,

        Specified by:
        evaluate in interface Function
        args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
        srcCellRow - row index of the cell containing the formula under evaluation
        srcCellCol - column index of the cell containing the formula under evaluation
        The evaluated result, possibly an ErrorEval, never null. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to Double.NaN be sure to translate the result to ErrorEval.NUM_ERROR.
