Read every netcdf files in a folder

folderData = 'D:\Valerio\data\TEST';
filePattern = fullfile(folderData, '*.nc'); 
ncfiles = dir(filePattern);
nFiles = length(ncfiles);

for i = 1:nFiles
    ncdisp(ncfiles(i).name);

    %file = 'ww3_outf_198501.nc';
    %ncdisp(file);
    lon = ncread(ncfiles(i),'x');
    lat = ncread(ncfiles(i),'y');
    %latitudine e longitudine

Hi everyone,

I have to read and do some operation on the every netcdf files in a folder. I did for loop to read all the file but it stops on the command 'ncdisp' and I obtain the error below.

Is there someone that can help me? Thank you so much.

Error using internal.matlab.imagesci.nc/openToRead (line 1272)
Could not open ww3_outf_198502.nc for reading.

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

Error in ncdisp (line 62)
ncObj   = internal.matlab.imagesci.nc(ncFile);

Try this with full path filename

folderData = 'D:\Valerio\data\TEST';
filePattern = fullfile(folderData, '*.nc'); 
ncfiles = dir(filePattern);
nFiles = length(ncfiles);

for i = 1:nFiles
    filename = fullfile(ncfiles(i).folder, ncfiles(i).name);
    ncdisp(filename);

    %file = 'ww3_outf_198501.nc';
    %ncdisp(file);
    lon = ncread(filename,'x');
    lat = ncread(filename,'y');
    %latitudine e longitudine
    H_s = ncread(filename,'Hs');
    T_m = ncread(filename,'Tm');
    D_m = ncread(filename,'Dm');
    time1 = ncread(filename,'time1'); %anno, mese e giorno
    time2 = ncread(filename,'time2'); %ore, minuti e secondi
end
