combining multiple .asc files to generate multidimensional raster

I have 5 of .asc files each of dimensions 18*34. I need to combine these files to generate a multidimensional matrix with dimensions 18*34*5.

I am using the following code; but the dimensions of output matrix are 1*1*5.

Where am I wrong?

path = 'E:\SPI';
Pattern = fullfile(path, 'CDR*'); 
Files = dir(Pattern);
A = []; 
for k = 1 : length(Files)
    baseFileName = Files(k).name;
    fullFileName = fullfile(path, baseFileName);
    fprintf(1, 'Now reading %s\n', fullFileName);
    data = importdata(fullFileName);
    A = cat(3, A, data);
    save('A.mat','A');
end
size(A)

Is importdata loading file correctly? You may try breakpoints to find the error: https://www.mathworks.com/help/matlab/matlab_prog/set-breakpoints.html.

Try this

path = 'E:\SPI';
Pattern = fullfile(path, 'CDR*'); 
Files = dir(Pattern);
A = cell(numel(Files)); 
for k = 1 : numel(Files)
    baseFileName = Files(k).name;
    fullFileName = fullfile(path, baseFileName);
    fprintf(1, 'Now reading %s\n', fullFileName);
    data = readmatrix(fullFileName);
    A{k} = data;   
end
A = cat(3, A{:})
save('A.mat','A');
