javascript - Google geolocation API adding coordinates and/or locations to a map -


i'm not sure question has been asked before situation have database 1/2 long/lat , 1/2 locations. prefer use long/lat because addresses may not accurate enough.

how put long/lat on google geolocation api map , combine addresses. example, if longitude == "" or null address.

javascript , html

     <div id="map" style="width: 500px; height: 400px;"></div> 

      var locations = [           ['bondi beach', -33.890542, 151.274856, 4],           ['coogee beach', -33.923036, 151.259052, 5],           ['cronulla beach', , , 3],           ['manly beach', , , 2],           ['maroubra beach', -33.950198, 151.259302, 1]           ];               // need here.     // if locations[i][1] empty locations[i][0].      // simple enough how find address  var map = new google.maps.map(document.getelementbyid('map'), {   zoom: 10,   center: new google.maps.latlng(-33.92, 151.25),   maptypeid: google.maps.maptypeid.roadmap });  var infowindow = new google.maps.infowindow();  var marker, i;  (i = 0; < locations.length; i++) {     marker = new google.maps.marker({     position: new google.maps.latlng(locations[i][1], locations[i][2]),     map: map   });    // bonus how put custom marker in , add nearest station    // need use different api or can same block.    google.maps.event.addlistener(marker, 'click', (function(marker, i) {     return function() {       infowindow.setcontent(locations[i][0]);       infowindow.open(map, marker);     }   })(marker, i)); }

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
