Concatenate multiple matrices by 3rd dimension using 'for' loop (considering a specific variable in netCDF files)

Hi. I've got a series of netCDF files (250) each having several variables. I read each file and extracted 'lwe_thickness' variable from each file. It's a 360*180 matrix in each. My objective is to concatenate these matrices by 3rd dimension and get the mean matrix by element for 'lwe_thickness'. I tried the following loop considering just 4 files, but it does not concatenate by 3rd dim. Could anyone please help me find what's going wrong here. (It gives All_LWE = -0.0070 -0.0157 -0.0215 -0.0259 as the ans). (LWE is transposed to agree with [lon] & [lat] dimensions which is for later use)

-Thank you in advance-

Folder = 'C:\Users\Matlab1\ncfiles';

Patternoffiles = fullfile(Folder, '*.nc');

ncfiles = dir(Patternoffiles);

n = length(ncfiles);

for i = 1:n

filename = fullfile(ncfiles(i).folder, ncfiles(i).name);

ncdisp(filename);

LWE=ncread(filename,'lwe_thickness');

LWE=LWE';

All_LWE=cat(3,LWE(1:n))

end

Folder = 'C:\Users\Matlab1\ncfiles';
Patternoffiles = fullfile(Folder, '*.nc'); 
ncfiles = dir(Patternoffiles);
n = length(ncfiles);
ALL_LWE = zeros(360,180,n) ;   % preallocate/ initialize 
for i = 1:n
    filename = fullfile(ncfiles(i).folder, ncfiles(i).name);
    ncdisp(filename);
    LWE=ncread(filename,'lwe_thickness');
    LWE=LWE';
    All_LWE(:,:,i) = LWE ;  % fill the matrix here 
end
