获取当前处理数组的上述值（excel中公式执行时的结果数组）

Question

I know how to get a value from an above cell of a cell with a formula being executed but I am struggling to do the same with an array. You can simply refer to the above cell and then let the drag function of excel do the magic for the other consequence cells.

However, doing that with a dynamic array that has a single formula is new to me. I want to be able to get the above (calculated) value of a result array (currently being executed by a formula).

Take a look at the attached picture, you can see at C3 I failed to refer to the above row of the result array. The expected column in E2 is what the result should be.

I hope my question is clear...

Your help is highly appreciated

Answer 1

I don't think this particular case merits the use of a recursive set-up. Simply:

=LOOKUP(ROW(B3#),ROW(B3#)/(LEFT(B3#,4)="Ref:"),RIGHT(B3#,2))

In any case, for the recursion you'd require a LAMBDA , for example:

=LAMBDA(δ,IF(δ<1,"",IF(LEFT(INDEX($B$3#,δ),4)="Ref:",RIGHT(INDEX($B$3#,δ),2),MyLambda(δ-1))))

stored in Name Manager as MyLambda , after which you can enter in the worksheet:

=MyLambda(ROWS($1:1))

and copy down as required.

I'm certain this LAMBDA could be improved, even made to spill a dynamic array, though as I said, it's really not necessary here.
