Mar 24, 2018 · I have around 9000 folders named ACCEDE00000 to ACCEDE08999 and each of them contains multiple csv files, but I'm only interested in one specific csv file named frame_table1_final.csv for each of 9000 ACCEDE videos. So I tried:

Feb 24, 2016 · Yes as you've stated, you want to store the filenames in an array (in this case an array of structures) and then loop through them and call csvimport on each of them. data{k} = csvimport(fullfile(basepath, files(k).name)); You can then access the resulting data within the data variable. Such as: For people who like short things...

Jul 18, 2019 · myfilename= sprintf ('%i.data',r); %file names as 1.data, 2.data and so on. Mydata = textscan (fid,'%f %f');% Assuming you have 2 columns of floating point data. Update as per your file accordingly. Hope this helps!! myfilename= sprintf …
