sprintf

I'm trying to get sprintf to print out a line that says: 'for event ----- stations pass the criteria test=' where it will list the results for my stations vertically like:

U02B.HHZf

U04B.HHZf

U05B.HHZf

U06B.HHZf

and so on. I can't seem to get it to do this..it keeps combining my stations together something like UUU00452648BBBB....HHHHHZZZZZfffff. I'm looking at the help pages but there are few examples, any suggestions? This is what I've written so far:

u=char(files(keep==1));
str1=sprintf('for event %s stations passed criteria
test=%f\n',char(dirs(i)),char(u));
disp(str1)

where u= U02B.HHZf

U04B.HHZf

U05B.HHZf

U06B.HHZf

and dirs(i) corresponds to my directories. Any suggestions or help in what I'm doing wrong?

Perhaps this helps:

Name = {'String1', 'String2', 'String3'};
Data = {1, 2, 3};
C    = cat(1, Name, Data);
fprintf('Name is %s, value is %d\n', C{:});

Name is String1, value is 1
Name is String2, value is 2
Name is String3, value is 3

Using a for loop for that would be easiest, probably.

Question: what value is it that you are trying to print out with the %f numeric format?

files = {'U02B.HHZf';'U04B.HHZf';'U05B.HHZf';'U06B.HHZf'};
keep = true(size(files));
dirs = {'some\directory'};
i = 1;

tmp = sprintf('%s\n',files{keep==1});
str1 = sprintf('for event %s stations passed criteria test=\n%s',char(dirs(i)),tmp);
disp(str1)

for event some\directory stations passed criteria test=
U02B.HHZf
U04B.HHZf
U05B.HHZf
U06B.HHZf

This wasn't an option when the question was originally asked, but in more recent releases I recommend storing the names as a string array.

S = ["U02B.HHZf"
"U04B.HHZf"
"U05B.HHZf"
"U06B.HHZf"]

S = 4x1 string array
    "U02B.HHZf"
    "U04B.HHZf"
    "U05B.HHZf"
    "U06B.HHZf"

passed = [true true false true] % 5B didn't pass, the others did

passed = 1x4 logical array
   1   1   0   1

sprintf("For event, station passed criteria test=%s\n", S(passed))

ans = 
    "For event, station passed criteria test=U02B.HHZf
     For event, station passed criteria test=U04B.HHZf
     For event, station passed criteria test=U06B.HHZf
     "

Or to display the header only once:

sprintf("For event, stations passed criteria test=\n%s", sprintf("%s\n", S(passed)))

ans = 
    "For event, stations passed criteria test=
     U02B.HHZf
     U04B.HHZf
     U06B.HHZf
     "
