 The `ParseTree()` from `opencv/modules/matlab/generator/parse_tree.py` takes this set of definitions and refactors them into a semantic tree better suited to templatization. For example, a trivial definition from the header parser may look something like:

 **mxarray.hpp**  
 mxarray.hpp defines a class called `MxArray` which provides an OOP-style interface for Matlab's homogeneous `mxArray*` type. To create an `MxArray`, you can either inherit an existing array
 
-	MxArray mat(prhs[0]);
+```cpp
+MxArray mat(prhs[0]);
+```
 	
 or create a new array
 
-	MxArray mat(5, 5, Matlab::Traits<double>::ScalarType);
+```cpp
-	MxArray mat = MxArray::Matrix<double>(5, 5);
+MxArray mat(5, 5, Matlab::Traits<double>::ScalarType);
+MxArray mat = MxArray::Matrix<double>(5, 5);
+```
 	
 The default constructor allocates a `0 x 0` array. Once you have encapculated an `mxArray*` you can access its properties through member functions:
 
-	mat.rows();
+```cpp
-	mat.cols();
+mat.rows();
-	mat.size();
+mat.cols();
-	mat.channels();
+mat.size();
-	mat.isComplex();
+mat.channels();
-	mat.isNumeric();
+mat.isComplex();
-	mat.isLogical();
+mat.isNumeric();
-	mat.isClass();
+mat.isLogical();
-	mat.className();
+mat.isClass();
-	mat.real();
+mat.className();
-	mat.imag();
+mat.real();
-	etc…
+mat.imag();
-	
+etc…
+```
+
 The MxArray object uses scoped memory management. If you wish to pass an MxArray back to Matlab (as a lhs pointer), you need to explicitly release ownership of the array so that it is not destroyed when it leaves scope:
 
-	plhs[0] = mat.releaseOwnership();
+```cpp
+plhs[0] = mat.releaseOwnership();
+```
 
 **bridge.hpp**  
 The bridge interface defines a `Bridge` class which provides type conversion between std/OpenCV and Matlab types. A type conversion must provide the following:
 
-	Bridge& operator=(const MyObject&);
+```cpp
-	MyObject toMyObject();
+Bridge& operator=(const MyObject&);
-	operator MyObject();
+MyObject toMyObject();
+operator MyObject();
+```
 	
 The binding generator will then automatically call the conversion operators (either explicitly or implicitly) if your `MyObject` class is encountered as an input or return from a parsed definition.
