Using indexing to find specific rows

2 views (last 30 days)
I have a .CSV file that has the latitude, longitude, and elevation in three columns. I would like to bring that into my code, so if a certain longitude is typed in, then the latitude and elevation associated would be the out put. I am having problems with the import feature, and the numbers keep rounding up which is not good for what I am doing. Any help is greatly appreciated.

There are a number of ways to read your file.
With respect to the rounding, that is only in the display. MATLAB maintains full internal precision.
With that in mind, however, the ismembertol funciton could be useful in retrieving the desired coordinates.

Awesome! I appreciate your response. I read how ismembertol works, but would it work with indexing? If I just copied and pasted my three columns into a vector array, would it still work?

Thank you!
Yes.
It returns a vector of logical elements. If you want specific numerical array indices, use find with it.
