printing in a loop

so I have a file customers.txt with names in the order of first to last such as

jones, juanita

ant, adam

and I need to reverse them and store into a variable custformat in the order of

juanita jones

adam ant

this is what i have so far

fid=fopen('customers.txt');
while feof(fid)==0
c=fgetl(fid);
[f b]=strtok(c,',');;
l=[b(3:end) ' '];
cusformat=[l f]
end

What exactly is your question?

[Walter Roberson]

Before the loop:

cusformat = {};

Inside the loop:

cusformat{end+1} = [l f];
