MATLAB: Loop to read files

Question

I have data_2010.csv, data_2011.csv,… in the same directory. I want to write a loop like

for i=2010:1:2020
    (table data_i)= readtable(data_i.csv)
end

Please advise.

Answer 1

To read all csv files one by one

files = dir('*.csv');
table_data = cell(1, numel(files));
for i=1:numel(files)
    filename = files(i).name;
    table_data{i} = readtable(filename);
end

To only read these specific files

range = 2010:1:2020;
table_data = cell(1, numel(range));
for i = 1:numel(range)
    filename = sprintf('data_%d.csv', range(i));
    table_data{i} = readtable(filename);
end
