在 MATLAB Online 中打开

d='E:\matlab'  % your folder
f=dir([d '\*.csv'])
for k=1:numel(f)
 data{k}=xlsread(f{k}.name);
end

If you want the data from the third file:

data{3}

Do not use a variable for each file.

What would be the easiest way about horizontally concatenating data tables saved in a cell array like above? I don't want to hard code it because the length of the cell array is subject to change. Essentially from above I have a resulting 1 * 8 cell array with tables of varying # of cols but same amount of rows. I wish to combine all the data from these files by the function join using the column "ID".

Thanks!
