The basic reason is because they are useful! | |

Also I moved submatrix() to MatrixBase, because we can make submatrix from view of matrix as well. Other operations like matrix addition and multiplication will be done upon MatrixBase! Cool!

| Apr 30, 2021 at 21:36 | comment | added | frozenca | Although constructing zero-length dimension matrix itself isn't illegal, you can't do anything meaningful with matrix that contains zero-length dimension (almost all operations will throw exceptions). That's why I didn't allow zero-length dimensions. | |

If you have const data members, then you can't assign to the object. He's also defining swap.
