How to efficiently find the first position in a specified range of data that meets the requirements?
For example, Big Class.jmp
The calculation steps are:if(row()>30,contains(:height[Index(1,30)],abs(:height[Index(1,30)]-:height)<3))
If the number of lines is greater than 30,
compare the data with the absolute value difference between the height of lines 1 -- 30 and the height of this line is less than or equal to 2, and calculate the number of lines 1 -- 30 that meet the above conditions first.Than...
