m.block<3,3>(1,0).setIdentity();
cout << m << endl;
* Merge Extract and Part to the Part expression. Renamed "MatrixBase::extract() const" to "MatrixBase::part() const" * Renamed static functions identity, zero, ones, random with an upper case first letter: Identity, Zero, Ones and Random. 2008-07-21 08:34:46 +08:00			`Matrix4i m = Matrix4i::Zero();`
Patch by Gael Guennebaud: unify fixed-size and dynamic-size Block expressions, update documentation. 2008-02-29 21:56:40 +08:00			`m.block<3,3>(1,0).setIdentity();`
-add set...() methods and their documentation; remove Generic -use row-major traversal when the number of columns is fixed and the number of rows is dynamic -other minor changes 2008-01-11 23:08:04 +08:00			`cout << m << endl;`
