I would like to import data from csv files from the folder. I used to "import data", but there is no possibility to import more than one file. So I want to remodel script which was generated by "import data". I have about 10-15 csv files in the folder. How can I do this? Give me any advice on importing the CSV files. Thank you. There is script generated by Matlab:

%%Initialize variables. 
filename = 'C:\...\laser 1\1km\TRACE904.CSV'; 
delimiter = ','; 
startRow = 14; 
%%Format string for each line of text: 
formatSpec = '%f%f%*s%[^\n\r]'; 
%%Open the text file. 
fileID = fopen(filename,'r'); 
%%Read columns of data according to format string. 
textscan(fileID, '%[^\n\r]', startRow-1, 'ReturnOnError', false); 
dataArray = textscan(fileID, formatSpec, 'Delimiter', delimiter, 'MultipleDelimsAsOne', true, 'ReturnOnError', false); 
%%Close the text file. 
fclose(fileID); 
%%Create output variable 
TRACE904 = [dataArray{1:end-1}]; 
%%Clear temporary variables 
clearvars filename delimiter startRow formatSpec fileID dataArray ans;
