- make MatrixBase and all expressions aware of their preferred traversal order. Honor this preference in operator=. - add several methods to the API - rework API for diagonal matrices - add benchmarking code 2008-01-05 18:57:14 +08:00			`Matrix4d m = Vector4d(1,2,3,4).asDiagonal();`
matrix storage order can now also be row-dominant (choosable for each matrix separately) map() moves from MatrixBase to Matrix much more documentation/examples/snippets 2007-12-28 05:43:10 +08:00			`cout << "Here is the matrix m:" << endl << m << endl;`
Patch by Gael Guennebaud: unify fixed-size and dynamic-size Block expressions, update documentation. 2008-02-29 21:56:40 +08:00			`cout << "Here is m.fixed<2, 2>(2, 2):" << endl << m.block<2, 2>(2, 2) << endl;`
			`m.block<2, 2>(2, 0) = m.block<2, 2>(2, 2);`
