Making 3d array using 2d arrays and how to do that

I have 438 files which are containing a 2d data. The size of the 2d data varies, sometimes the size is 215x3245 and sometimes this is 215x3246. Now my objective is to make a 3d array od 438x215x3245 or 438x215x3246. I have written the code like below :

files_jan = dir('S5P_OFFL_L2__CH4____2019*.*'); 
h = zeros(215,3245,438); 
for j = 1:438
h(:,:,j) = ncread(files_jan(j).name,'/PRODUCT/methane_mixing_ratio'); % Note that I shifted j to the third position
end

This code is giving error,as i prelocate the data size of 215x3245x438 and sometimes the right side has a dimension of 215x3246x438. How can i solve this problem?

files_jan = dir('S5P_OFFL_L2__CH4____2019*.*'); 
h = zeros(215,3245,438); 
for j = 1:438
    temp = ncread(files_jan(j).name,'/PRODUCT/methane_mixing_ratio'); % Note that I shifted j to the third position
    if size(temp,1) ~= 3245
        temp = imresize(temp,[3245 438]) ; 
    end
    h(j,:,:) = temp ; 
end

I got an error like this:

Unable to perform assignment because the size of the left side is 215-by-3245 and the size of the right side is

3245-by-438

Ohh..yes edited the code....

Thanks for your response. But again I got error :

Error using netcdflib

The NetCDF library encountered an error during execution of 'open' function - 'HDF error (NC_EHDFERR)'.

Error in netcdf.open (line 67)

[varargout{:}] = netcdflib ( 'open', filename, varargin{1} );

Error in internal.matlab.imagesci.nc/openToRead (line 1278)

this.ncRootid = netcdf.open(this.Filename,'NOWRITE');

Error in internal.matlab.imagesci.nc (line 121)

this.openToRead();

Error in ncread (line 61)

ncObj = internal.matlab.imagesci.nc(ncFile);

This was stopped at j = 42

This is a different error. Check your ncfile, is the file corrupt or does the file exist or does the file have said variable.

Try reading the file seperately.

okay I will check these things. I want to what did you write in your code. Can you please explain the if loop. I could not understand that part. Thank you.
