I'm using the following line but can't seem to get it working: "=" & strProjectName & "!" & Cells(2, 7).Address Any advice on why this isn't working or a prod in the right direction would be greatly appreciated. Thanks in advance 回答1: Not sure what isn't working in your case, but the following code will put a formula into cell A1 that will retrieve the value in the cell G2.

In cell B16 I want to count how many "B"s (the value in A16) are in cells C1:C15 and A16. Then using some function I will put an "A" or "B" in cell C16. How can I give such a range in COUNTIF? The same formula must be used for every cell in column B. 回答1: Here's the formula for cell B16: =SUM(COUNTIF(INDIRECT({"C1:C15","A16"}),"B")) 回答2: As an alternative that would work for copying

Verify if point is inside a cone in 3D space

由 自闭症网瘾萝莉.ら 提交于 2019-11-27 02:24:02
问题 Consider: X(x1,y1,z1) the point I need to verify if it is inside a cone. M(x2,y2,z2) the vertex of the cone. (the top point of the cone) N(x3,y3,z3) the point in the middle of the cone's base. I found out that if a point X is on the cone, it needs to verify this equation: cos(alfa) * ||X-M|| * ||N|| = dot(X-M,N) Where dot is the scalar product of 2 vectors, and alfa is the angle between these 2 vectors. Based on the formula, I calculated that: X-M = (x1-x2,y1-y2,z1-z2) So, cos(alfa) * Math

Optimizing Excel formulas - SUMPRODUCT vs SUMIFS/COUNTIFS

由 为君一笑 提交于 2019-11-27 02:12:19
According to a couple of web sites, SUMIFS and COUNTIFS are faster than SUMPRODUCT (for example: http://exceluser.com/blog/483/excels-sumifs-or-sumproduct-which-is-faster.html ). I have a worksheet with an unknown number of rows (around 200 000) and I'm calculating performance reports with the numbers. I have over 6000 times almost identical SUMPRODUCT formulas with a couple of difference each times (only the conditions change). Here is an example of what I got: =IF(AFO4>0, (SUMPRODUCT((Sheet1!$N:$N=$A4) *(LEFT(Sheet1!$H:$H,2)="1A") *(Sheet1!$M:$M<>"service catalog") *(Sheet1!$J:$J="incident")

Simulate string split function in Excel formula

由 ￡可爱￡侵袭症＋ 提交于 2019-11-27 02:05:09
问题 I am trying to split a string in an excel formula, something like I can do in many programming languages, e.g. string words = "some text".split(' '); The problem is that I can't be sure that there is more than one word in the cell. If I try to use the FIND() or SEARCH() functions, they return #VALUE if there is not space. Is there any easy way to split the string so that it returns the individual words (or even better, so that it returns either the first word or all the other words)? 回答1: A

Shortcut using lm() in R for formula

由 戏子无情 提交于 2019-11-26 23:36:17
问题 It is possible to use a shortcut for formula in lm() m <- matrix(rnorm(100), ncol=5) lm(m[,1] ~ m[,2:5] here it would be the same as lm(m[,1] ~ m[,2] + m[,3] + m[,4] + m[,5] but in the case when variables are not of the same level (at least this is my assumption for now) this does not work and I get the error: Error in model.frame.default(formula = hm[, 1] ~ hm[, 2:4], drop.unused.levels = TRUE) : invalid type (list) for variable 'hm[, 2:4]' Data (hm): N cor.distance switches time 1 50 0

Get formula from Excel cell with python xlrd

由 一曲冷凌霜 提交于 2019-11-26 22:32:29
I have to port an algorithm from an Excel sheet to python code but I have to reverse engineer the algorithm from the Excel file . The Excel sheet is quite complicated, it contains many cells in which there are formulas that refer to other cells (that can also contains a formula or a constant). My idea is to analyze with a python script the sheet building a sort of table of dependencies between cells, that is: A1 depends on B4,C5,E7 formula: "=sqrt(B4)+C5*E7" A2 depends on B5,C6 formula: "=sin(B5)*C6" ... The xlrd python module allows to read an XLS workbook but at the moment I can access to
