function that takes a vector and returns negative numbers and position

I'm looking to create a function that will take a vector and return all the negative values in one vector and their position in another vector. So, for example,

% output:
v = [-1 4 6 2 -3]

% output:
vneg = [-1 -3]
pos  = [1 5].

any help is appreciated!

One simple solution to get the negative values and their index.

x = [4 3 -2 9 -7 31];

index = find(x<0);
-> index = 3 5

x_new = x(index);
-> x_new = -2 -7

Just change the condition in the find function as per your requirement.
