can i access field by using values in structure?

if there is some structure with different fields and the field also have lots of values . can we access field by using value?

like we don't know anything about struct or field , we just have values in our hand so can we find which field contains certain value?

S = struct ;
S.name = {'Tom' 'Dick' 'Harry'} ;
S.sex = {'M' 'M' 'F'} ;
S.Age = [16 17 18] ;

val = 'F' ; 
fields = fieldnames(S) ; 
for i = 1:length(fields)
    vals = getfield(S,fields{i}) ;
    [c,ia]= ismember(vals,val) ;
    if any(c)
        fprintf('given value  is present in %s field\n',fields{i}) ;
    end
end

given value  is present in sex field

i can't understand the last ffifth line

[KSSV]

val = 'F' ;

It is the value in which I am interested to find whether present in the structure.

Yes you can save. Read about save

actually, i want to make a list of all the outcomes of if -condition and save it in variable.
