formula

问题 I'm trying to count if the following range is "Y" or "S" and contains numbers. I'm trying to exclude cells beginning with "_PVxxxxx_" . I cant use COUNTIFS($A:$A,">0",$B:$B,"Y") + COUNTIFS($A:$A,">0",$B:$B,"S") because the formula considers "_PVxxxxx_" to be more than 0 and includes them in the calculation. Can anybody help? Thanks alot! 回答1: The function SUMPRODUCT is quite versatile, typically more flexible for testing than COUNTIFS and SUMIFS . It should do the trick (see e.g. https:/

问题 I wrote some code that calculates the determinant of a given nxn matrix using Leibniz formula for determinants. I am trying to figure out it's complexity in O-notation. I think it should be something like: O(n!) * O(n^2) + O(n) = O(n!*n^2) or O((n+2)!) Reasoning: I think O(n!) is the complexity of permutations. and O(n) the complexity of perm_parity, and O(n^2) is the multiplication of n items each iteration. this is my code: def determinant_leibnitz(self): assert self.dim()[0] == self.dim()

问题 I've tried a few formula options but nothing is quite working the way I would like it to. I'm using a very simple SUM formula to total across all the worksheets in my workbook. Currently it's set up like this: =SUM('1:10'!D3) However, I'm likely going to add more worksheets and I want them included in this total. I've tried a few different versions of "wshNameLast" or "getlastwsname" that I've found in different articles here but they are all giving me a #REF error. Is there a formula I'm
