I hope someone can help. Below is a slapped together code with the idea.
x = [2 20 4 51 60]
g = diff(x)
% so that g give me g = [-18 16 -47 -9]
%max(g) gives 16 in this case
I want the two numbers that make up the 16 set to variables like V and W. However, I dont want to just call the x matrix again to do it so that this can be more robust. Does something like this exist?
Some output that gives me V = 20 and W = 4

You could write your own function to do this. However, I'm not aware of anything that does this already. Especially since you are working with g but want results from x.
Note that one of the syntax options for max is to return the index of the value.
[M,I] = max(___)
