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
