Index exceeds array bounds

Hi

When I run my code, I got the error "Index exceed array bounds. I am not sure what it's mean?

I got it in the line "z{i} = ncread(ncfiles(i).name,'z',[1 1 n],[nx ny 1]);"

for i = 1:Nfiles
  lon{i} = ncread(ncfiles(i).name, 'longitude'); nx = length(lon{i});
  lat{i} = ncread(ncfiles(i).name, 'latitude'); ny = length(lat{i});
  time{i} = ncread(ncfiles(i).name, 'time'); nt = length(time{i});
  z{i} = ncread(ncfiles(i).name, 'z'); nz = length(z{i});                                                                                                                                      
end

I am not going to understand what you mean but see the example below:

x=1:10
x(11) % you will get the error INDEX EXCEEDS ARRAY BOUNDS

When you try to access the element of an array than it's existence you will get an error.
