markwhilesumle,markwhilesumge

Marks each cell in specified order until the sum reaches a specified limit.

Result = markwhilesumle(expression1, expression2, limit)
Result = markwhilesumge(expression1, expression2, limit)
expression1
ordinal, spatial
expression2
scalar, spatial, non spatial
limit
scalar, non spatial
Result
boolean, spatial

Operation

Each cell of expression2 is summed in the order specified by the ascending ordinal values in expression1 while the sum of the cells in expression2 is less or equal than limit for markwhilesumle, or greater or equal than limit for markwhilesumge. Result is a boolean map where every cell that matches the condition is marked 1 (True) or 0 (False) otherwise.

Notes

Missing values in expression1 or expression2 will return missing values in Result. expression1 should have an ascending order with no multiple instances of the same number.

Examples

  1. • pcrcalc
    binding
    Result2 = Result2.map;
    Expr1 = Expr1.map;
    Expr = Expr.map;
    initial
    report Result2 = markwhilesumge(Expr1, scalar(Expr), 40);

    • python
    Expr1 = readmap(“Expr1.map”)
    Expr = readmap(“Expr.map”)
    Result2 = markwhilesumge(Expr1, scalar(Expr), 40)
    Result2.map Expr1.map Expr.map

  2. • pcrcalc
    binding
    Result1 = Result1.map;
    Expr1 = Expr1.map;
    Expr = Expr.map;
    initial
    report Result1 = markwhilesumle(Expr1, scalar(Expr), 40);

    • python
    Expr1 = readmap(“Expr1.map”)
    Expr = readmap(“Expr.map”)
    Result1 = markwhilesumle(Expr1, scalar(Expr), 40)
