Origin Pro 8.6 and Service Release b70 (Select Help-->About Origin):
Operating System: 32-bit, Window 7
Hello Guys!
I am writing for your help!
It is about the function ave(vd,n).
For example, I defined natural numbers in the column A(x) from row 1 to 40. I want to calculate the average of the col(A). I set the value: Col(B)=ave(col(A),40) and "apply".
The first row of Col(B) shows the right answer.
However,
1. Why the result is zero, when I chose the row 2 of Col(B)and "apply" ?
2. In another case, it was always no result, even in the first row! No matter how I used ave(col(f),n)or ave(col("Long Name"),n), masked the selected range or not.
I am  .
Thank you for your time!
Looking forward to your reply!

For the 2nd question, after i duplicated the sheet, the ave() function works again! However, I don't know what happened. |

The ave( ) returns a vector (a dataset) and assignment to a column always begins at row 1. You can use the row From and To in Set Values to limit the results to certain rows, but this does not shift results.
Anytime the group number (the second argument) is greater than the number of points in the source dataset (the first argument), the returned vector is empty.
The number of points returned is the integer larger than or equal to the number of points in source data divided by the group number.
