I have several csv files and want to read this file in a loop, the files are called a1.csv, a2.csv, a3.csv I can read those files like this
csvfiles = dir('*.csv')
for file = csvfiles'
fprintf(1,'Doing something with %s\n',file.name)
end
Within this loop I have to do some calculation with the data of each file. After this I want to store the output in several files according to the original name like a1_output.txt, a2_output.txt, a3_output.txt. Any help how I can do this?

csvfiles = dir('*.csv')
filenames = {csvfiles.name}
for fn = filenames
fprintf(1,'Doing something with %s\n', char(fn))
[~, n] = fileparts(char(fn));
outfn = [n '_output.txt']
end
