+##
+##   UDXoutput2Dtimeseries(filename,p,t,u,attr_name,attr_rank,attr_shape,time)
+##
+##   Outputs data in DX form.
+##   Only one variable can be written to the file
+##   variable must be a scalar, vector or tensor of doubles   
+##
+##   attr_name  = name of the variable                   (type string)
+##   attr_rank  = rank of variable data                  (0 for scalar, 1 for vector, etc.)
+##   attr_shape = number of components of variable data  (assumed 1 for scalar)
+##
