Read from Matlab and write to a field on webpage

I have got some output in Matlab (latitude and longitude using a GPS device) and would like to send these info to a website http://www.latlong.net/Show-Latitude-Longitude.html to the "latitude" and "longitude" fields to see the position on the map. This needs to be done only by running my .m file on Matlab. Does anybody have any idea on that?

Thanks
