How can we convert struct file to txt file?

We have a 5x1 struct file as you can see in the picture. IDs represent the names of the patients, so we have 5 patients. We want to save sounddata and flow data for each patient separately as txt file.

arrayfun(@(s) writematrix([s.S s.F],[s.ID '.txt']),structWheeze)

It shows an error i dont know why. it says S is undefined even though I have defined it. Also how can I loop for every patient? I want to write them all in a loop instead of typing them one by one for each patient but I couldn't. Can you help?

Need see what you did and exact error message in context -- works here...

>> structWheeze
structWheeze = 
  1×2 struct array with fields:
    ID
    S
    F
>>
>> structWheeze.ID
ans =
    'yk103'
ans =
    'yk104'
>> 
>> arrayfun(@(s) writetable(struct2table(s,'AsArray',1),[s.ID '.txt']),structWheeze)
>> dir yk*.txt

yk103.txt  yk104.txt  

>>
>> type yk103.txt

ID,S_1,S_2,S_3,S_4,S_5,S_6,S_7,S_8,S_9,S_10,S_11,S_12,F_1,F_2,F_3,F_4,F_5,F_6,F_7,F_8,F_9,F_10,F_11,F_12
yk103,0.763916133953646,0.515979575398736,0.9985396037323,0.131498155852354,...

thank you so much! i fixed it but there is a little problem that i couldnt fix. I coulndnt assign a loop i mean if there are 20 patients i dont wanna write code for one by one. Instead of this i wanna assign a loop and it will show me all patients txt files. can you help me?

That's what arrayfun does ... did you try it and see what you got?

>> dir yk*.txt
yk103.txt  yk104.txt  

See??? There are two elements of the sample struct and two text files were created with the IDs in the array...

>> structWheeze.ID
ans =
    'yk103'
ans =
    'yk104'
