i working on simple linear interpolation program. , having troubles when implementing algorithm. assuming there 12 numbers whole, we'll let user input 3 of them(position 0, position 6 , position 12). program calculate other numbers. here piece of code achieve this: static double[] interpolate(double a, double b){ double[] array = new double[6]; for(int i=0;i<6;i++){ array[i] = + (i-0) * (b-a)/6; } return array; } static double[] interpolate2(double a, double b){ double[] array = new double[13]; for(int i=6;i<=12;i++){ array[i] = + (i-6) * (b-a)/6; } return array; } as can see, used 2 functions. want find universal function job. however, don't know how find common way represent i-0 , i-6 . how fix it? according floating point linear interpolation , know maybe should add formal parameter float f . not quite understand float f mean , how modify code based on it. me? thank you. if want interpolate intervals d...

i have google maps implemented on page , want able resize , recenter after particular event. here code have found on internet: var center = map.getcenter(); google.maps.event.trigger(map, "resize"); map.setcenter(center); now cool dont have access "map" global. instead have been able use jquery selector map-canvas dom so: google.maps.event.trigger($("#map-canvas")[0], 'resize'); but using $("#map-canvas")[0]; doesnt work when try call getcenter() , setcenter(). ideas why? thanks your map variable instance of google map object, $("#map-canvas")[0] dom element, can't call method because google won't recognize it. in case, may scope problem why don't put map variable global , call everywhere e.g: var map; // google map object $(document).ready(function(){ var center = map.getcenter(); google.maps.event.trigger(map, "resize"); map.setcenter(center); }); and then, whenever...

i have following, var = 0; $('.more').click(function(){ $.ajax({ type:"post", data{"num":i}, url:theurl, success:function(html){ $container.append(html); = i+18; etc. when post data , in php echo $_post['num']; getting error "syntax error, unrecognized expression: 0" , bunch of html following it. when don't include data number 0 works fine. going wrong here? if argument append doesn't begin html tag, it's treated jquery selector. should either wrap in div: $container.append("<div>" + html + "</div>"); or use .html() instead of .append() $container.html(function(i, oldhtml) { return oldhtml + html; });
