[Qgis-user] Azimuth from polyline?

[Antonios Marsellos]

Dear all,
 Is there any way to calculate the azimuth of many polylines of the same
layer or shapefile, and finally store it in a new field (that is a column in
the attributes table of this shapefile). This is easy in ArcGIS using
EasyCalculate, is there a similar way in QGIS?
