MATLAB: Make a plt from a 4-D multi array variable from nc file

4 d arraync file

I have a nc file with:
Dimensions:
time = 8
depth = 48
latitude = 109
longitude = 25
and make this:
u='global-reanalysis-phy-001-030-daily_1591804259623.nc'
ncdisp(u)
east = ncread(u,'uo'); 
lat = ncread(u,'latitude'); 
lon = ncread(u,'longitude');
time=ncread(u, 'time');
depth=ncread(u, 'depth');
dtime = datetime(1950, 1, 1, time, 0, 0);
jd=juliandate(dtime);
plot(lat, east(:,:,15,1));
east is a 4-D 8371200 double
But I want a plot (surfc) in time, this 8 days, latitude, one depth (lets say 48, the last) and the east variable that is a velocity m/s.
Any idea? What I should do with east variable? squeeze, quiver, etc realy dont know or find solution
Thanks.

ncfile = "global-reanalysis-phy-001-030-daily_1591804259623.nc";
time = ncread(ncfile,'time') ; 
depth = ncread(ncfile,'depth') ; 
lat = ncread(ncfile,'latitude') ;
lon = ncread(ncfile,'longitude') ; 
u = ncread(ncfile,'uo') ; 
% plots 
for i = 1:length(time)  % time loop
  for j = 1:length(depth) % depth loop
    z = u(:,:,j,i)' ;  % extract the matrix here 
    pcolor(lon,lat,z) ;
    colorbar
    shading interp
    xlabel('lon')
    ylabel('lat')
    title(sprintf('time = %d, depth = %d',i,j))
    drawnow
 end
end
