exclude category from get_posts?

getting posts by cat with get_posts but need to exclude another cat called london or id 10. is this possible?

best, Dc.

//  array(7,-10)
    $laargsM = array('category' => 7, 'posts_per_page'=>300, 'orderby'=>'title', 'order'=>'asc' );
    $la_shapes = get_posts( $laargsM ); 

as ‘get_posts()’ uses the ‘WP_Query()’ parameters, i would assume that this should work:

$laargsM = array(
    'cat'              => 7,
    'posts_per_page'   => 300,
    'orderby'          => 'title',
    'order'            => 'asc',
    'category__not_in' => array(10) 
);
