Storing variables in for loop

Hello! I am trying to create a for loop to store 16 different .csv files. The issue I am running into is that the for loop is only saving the last .csv file (file 16). I understand that the for loop is overwriting the "forcedData" variable with every iteration but I've tried using:

forcedData(k) = csvread(fileName,3,0);

and

forcedData(:,k)= csvread(fileName,3,0);

But neither of these work due to the number of elements being different on each side. I am fairly new to MATLAB so if anyone knows how to fix this issue so that I may have 16 different data sets in the forcedData variable, please help! I have included my scipt so far below this line:

for k = 1:16

%importing csv files

if k <=16

fileName = sprintf('forced_%d.csv',k);

end

if isfile(fileName)

forcedData(:,k)= csvread(fileName,3,0);

else

fprintf('File %s does not exist.\n',fileName);

end

end

Use a cell array, just like the documentation shows:

csvFiles = dir('*.csv') ; 
N = length(csvFiles) ; 
iwant = cell(N,1) ; 
for i = 1:N
    iwant{i} = csvread(csvFiles(i).name) ; 
end
