Basic Question! (how to find row number with certain value?)

Share icon

It would be very simple question...that I cannot solve yet...

There is a wave with linearly increasing values.
Among them, I want to find out the row number of certain value.
is there any proper built-in function in igor?

Thank you in advance.
And also BinarySearch and BinarySearchInterp if the values in your wave are monotonically increasing or decreasing.
