matlab - Implementation of GUIDE GUI buttons -

-

i have question implementation of buttons inside guide framework. have 2 buttons created , drop down menu not seen in below code (referenced in numc line). way program meant run select drop down menu, generate button takes directly drop down menu. third button, optimize, needs numc variable , cities matrix. possible reference them directly in optimize function, or first have use output feature in generate button make 2 usable. numc easy enough recapture using same line in generate, need cities matrix it's generated.

function optimize_callback(hobject, eventdata, handles) % hobject    handle optimize (see gcbo) % eventdata  reserved - defined in future version of matlab % handles    structure handles , user data (see guidata)  % --- executes on button press in generate. function generate_callback(hobject, eventdata, handles) % hobject    handle generate (see gcbo) % eventdata  reserved - defined in future version of matlab % handles    structure handles , user data (see guidata) numc = get(handles.numcities, 'value'); numc = numc*10; cities = rand(numc,2); cla                                         %clears current window plot(cities(1:numc,1),cities(1:numc,2),'r') hold on plot(cities(1:numc,1),cities(1:numc,2),'*')

you can use guidata command save data handles structure , make available other function. note how in above code, comment handles reads structure handles , user data (see guidata). can this

% --- executes on button press in generate. function generate_callback(hobject, eventdata, handles) % hobject    handle generate (see gcbo) % eventdata  reserved - defined in future version of matlab % handles    structure handles , user data (see guidata)  % etc. have above  % save data handles.numc   = numc; handles.cities = numc; guidata(hobject,handles);

in body of optimize_callback function, numc , cities should directly accessible handles handles.numc , handles.cities respectively.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
