Hello! I have a 1 dimensional array of latitude values (which has dimensions of 1 X 224). How would I calculate the change in latitude, aka delta latitude?
Thank you so much!

If they are decimal values, use the diff function. Otherwise, you will have to convert them into decimal values (from degrees-minutes-seconds) first.

Subtract the two latitudes you want to calculate the difference between? Or am I missing something?

That's what diff() does. Just make sure your angles are in decimal degrees or radians and not some kind of funky degrees/minutes/arcseconds form.

According to the online documentation, the Mapping Toolbox has the dms2degrees function that does the same thing. I suggest you use it instead of the one I provided. (I don’t have the Mapping Toolbox, so just now thought to look.)
