Hello Friends,
I have several csv files, all stored in path 'C:\Users\Name\Documents\MATLAB\*.csv'. I want to loop one by one each file in order, convert them into arff files, and save them 'C:\Users\Name\Documents\MATLAB\*.arff'

datadir = 'C:\Users\Name\Documents\MATLAB';
d = dir(fullfile(datadir, '*.csv'));
for i=1:length(d)
filename = fullfile(datadir, d(i).name);

It would be much more robust to use regexprep rather than indexing and string concatenation, something like this:
>> name = 'MyFile.csv';
>> regexprep(name,'\.csv$','.arff')
ans =
MyFile.arff
