+Description
+-----------
+
+Performs an axis-aligned traspose of a :ref:`MDHistoWorkspace <MDHistoWorkspace>`. Default *Axes* setting gives not transpose. It is possible to remove dimensions from the input workspace by omitting those dimension indexes from the *Axes* property. *Axes* are zero-based indexes.

+Usage
+-----
+
+**Example - TransposeMD**
+
+.. testcode:: TransposeMDExample
+
+   def print_dims(ws):
+       for i in range(ws.getNumDims()):
+           print 'Dimension %i is %s' % (i, ws.getDimension(i).getName())
+
+   mdws = CreateMDWorkspace(Dimensions=3, Extents='-10,10,-10,10,-10,10', Names='A,B,C',          Units='U,U,U')
+   FakeMDEventData(InputWorkspace=mdws, PeakParams='500000,0,0,0,3')
+   binned = BinMD(InputWorkspace=mdws, AlignedDim0='A,0,10,100',    AlignedDim1='B,-10,10,100', AlignedDim2='C,-10,10,1')
+   print 'Dimensions before',  binned.getNumDims()
+   print_dims(binned)
+   # Transpose the workspace
+   transposed = TransposeMD(binned, Axes=[1,0])
+   print 'Dimensions after', transposed.getNumDims()
+   print_dims(transposed)
+
+Output:
+
+.. testoutput:: TransposeMDExample
+
+   Dimensions before 3
+   Dimension 0 is A
+   Dimension 1 is B
+   Dimension 2 is C
+   Dimensions after 2
+   Dimension 0 is B
+   Dimension 1 is A
