Creating a matrix from vectors to have unique combinations

I am trying to populate a nx3 matrix such that every row is a unique combination. Here are my variables.

lat = (-25:0.1:-16);
lon = (-76:0.1:-64);
dep= [0:1:300];

What I am trying to get is a matrix that with length(lat)*length(lon)*length(dep) rows and 3 columns and should consist of every possible combination of lat, long and depth. For example, for a specific lat/long combination there should be 300 values. I feel like this should be very simple but I am not able to figure it out.

lat = (-25:0.1:-16)
lon = (-76:0.1:-64)
dep= [0:1:300]
[x,y,z]=meshgrid(lat,lon,dep);
out=[x(:) y(:) z(:)];
