How to import a set of NetCDF Files?

Hallo, Does someone know how to import a complete Dataset of NetCDF files. I have 54 files representing the sea levels from 1948 to 2011. so far I know how to read one file with ncread but I couldnt't find out how to import the entire set of the files.

ncfiles = dir('*.nc') ;    % you are in the folder where nc files are present 
N = length(ncfiles) ;   % number of files 
% loop for each file 
for i = 1:N
    thisfile = ncfiles(i).name; 
    % load the data and do what you want
end

hallo, thank you for your help! now I have a structure with all the files. I usually read the file name then load the variables as the following code or through ncread how should I load the data and read the files from the structure? sorry it may be easy but I am still a beginner at MATLAB!

if true
  % code
variables_to_load = {'lat' , 'lon' ,   'time' , 'e'}  
% loop over the variables
for j=1:numel(variables_to_load)
  % extract the jth variable (type = string)
  var = variables_to_load{j}
  % use dynamic field name to add this to the structure
  data_struct.(var) = ncread(filename,var);
  % convert from single to double
  if isa(data_struct.(var),'single')
      data_struct.(var) = double(data_struct.(var));
  end
end
lat=getfield(data_struct,'lat');
lon = getfield(data_struct,'lon');
e= getfield(data_struct,'e');
time= getfield(data_struct,'time');

end

ncfiles = dir('*.nc') ;
variables_to_load = {'lat' , 'lon' ,   'time' , 'e'} ;
for i = 1:length(ncfiles) ;
    % loop over the variables
    filename = ncfiles(i).name ;
    for j=1:numel(variables_to_load)
        % extract the jth variable (type = string)
        var = variables_to_load{j}
        % use dynamic field name to add this to the structure
        data_struct.(var) = ncread(filename,var);
        % convert from single to double
        if isa(data_struct.(var),'single')
            data_struct.(var) = double(data_struct.(var));
        end
    end
    lat=getfield(data_struct,'lat');
    lon = getfield(data_struct,'lon');
    e= getfield(data_struct,'e');
    time= getfield(data_struct,'time');
end

YOur code can be further simplified.

I tried to do so, it gives me back 3 errors regarding ncread

Error using internal.matlab.imagesci.nc/openToRead (line 1272) Could not open cD-2_TRIM-NP-2d-Baltic_6.4_e_001.nc for reading.

Error in internal.matlab.imagesci.nc (line 121) this.openToRead();

Error in ncread (line 53) ncObj = internal.matlab.imagesci.nc(ncFile); Do you have an idea, why I am getting these errors?

Have you sorted out this problem? I encounter the same problem this days. I have no idea about that. Thanks !
