how calculate distance between 2 markers in google maps v3? (similar distancefrom function inv2.)

thanks..

if want calculate yourself, can utilize haversine formula:

var rad = function(x) { homecoming x * math.pi / 180; }; var getdistance = function(p1, p2) { var r = 6378137; // earth’s mean radius in meter var dlat = rad(p2.lat() - p1.lat()); var dlong = rad(p2.lng() - p1.lng()); var = math.sin(dlat / 2) * math.sin(dlat / 2) + math.cos(rad(p1.lat())) * math.cos(rad(p2.lat())) * math.sin(dlong / 2) * math.sin(dlong / 2); var c = 2 * math.atan2(math.sqrt(a), math.sqrt(1 - a)); var d = r * c; homecoming d; // returns distance in meter };

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...
