 The :ref:`algm-Integration` algorithm is used to sum up each
 spectrum between XMin & XMax.
 
+Usage
+-----
+**Example - Sum rows of a 128*128 workspace**
+
+.. testcode:: ExSumRowColumnSimple
+
+   # Create a workspace with 128*128 spectra each with 5 values (only 128*128 or 192*192 are valid)
+   ws = CreateSampleWorkspace("Histogram",  NumBanks=1, BankPixelWidth=128, BinWidth=10, Xmax=50)
+
+   # Run algorithm with Horizontal orientation
+   OutputWorkspace = SumRowColumn( ws, "D_H")
+
+   print  "Input workspace has",ws.getNPoints(),"points."
+   print  "Output workspace has",OutputWorkspace.getNPoints(),"points."
+
+Output:

+.. testoutput:: ExSumRowColumnSimple
+
+   Input workspace has 81920 points.
+   Output workspace has 128 points.
