IMHO, the addition of interpretation is the whole point of a linear algebra 
library. Without this meaning, it's just a block of data, and, IMHO, 
attaching the name "matrix" to it doesn't make sense. E.g., multi_array

boost::multi_array< double, 2 > m_data;

or "2d_valarray" would much better fit the description for something that 
provides "size1" and "size2". Without interpretations in the context of 
linear algebra, we might as well allow

A = op1( b, op2( c ) );

and refer users to the manual :-).
