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

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