I use command: [status,result] = system('arp -a') to get the IP address in my machine, then I want to organize these info into a cell format. but I found that, after I remove the empty cells, there are still some cells looks empty but not.
below is the test code:
[status,result] = system('arp -a')
test=regexp(result,' ','split');
test=test(:);
ept_sig=[];
sig=1;
for i=1:1:length(test)
if isempty(test{i})
ept_sig(sig)=i;
sig=sig+1;
end
end
test(ept_sig)=[];
there are some variables in the resulted 'test' that looks like empty, but not.
what is that, is there any way to remove them?
Thanks!
Yu

test=regexp(result, '\s+','split');
In particular, you were dealing with newline and possibly carriage return as well.
