title: Conversion from Popular Visualisation Pseudo Mercator to spherical (WGS84) coordinates in Matlab
body: <p>I have an array of x &amp; y coordinates in the Popular Visualisation Pseudo Mercator projection (EPSG 3857) and wish to convert it to the normal lat/long spherical projection system (EPSG: 4326) in Matlab. 
  In Open Earth Toolbox there is a routine which is used for conversion of co-ordinates, although, conversion to and from Popular Visualisation Pseudo Mercator is not yet supported. </p>
  
  <p>Does anyone have any information regarding the conversion? A formula to guide can also be helpful which I can integrate in Matlab.</p>
  
  <p>Thanks!</p>
