hi, i have a few structure eg
s(1).name = 'james';
s(1).num = 999;
s(2).name = 'hoper';
s(2).num = 111;
i want to save all of this this a database.
the next time i want to find the attributes, for example i find hoper in the database, i want the corresponding structure field .num to be displayed.
how can i do the above tasks? help..
thank you for your reply

I hope the following helps you:
var_found = 22; % variable found in database
%example struct
s.name='ww';
s.age=22;
n=fieldnames(s); % fieldnames within the struct
for k=1:numel(n)
if s.(n{k})==var_found
wanted_field = n{k}; % the field containing the value found in the database
break
end
end
