Detailed Description
template<class T, class MATRIX_TYPE>
class oomph::Matrix< T, MATRIX_TYPE >
Abstract base class for matrices, templated by the type of object that is stored in them and the type of matrix. The MATRIX_TYPE template argument is used as part of the Curiously Recurring Template Pattern, see http://en.wikipedia.org/wiki/Curiously_Recurring_Template_Pattern The pattern is used to force the inlining of the round bracket access functions by ensuring that they are NOT virtual functions.

Output function to print a matrix row-by-row, in the form a(0,0) a(0,1) ... a(1,0) a(1,1) ... ... to the stream outfile. Broken virtual since it might not be sensible to implement this for some sparse matrices.
