Expression of a diagonal/subdiagonal/superdiagonal in a matrix.
MatrixType | the type of the object in which we are taking a sub/main/super diagonal |
DiagIndex | the index of the sub/super diagonal. The default is 0 and it means the main diagonal. A positive value means a superdiagonal, a negative value means a subdiagonal. You can also use Dynamic so the index can be set at runtime. |
The matrix is not required to be square.
This class represents an expression of the main diagonal, or any sub/super diagonal of a square matrix. It is the return type of MatrixBase::diagonal() and MatrixBase::diagonal(Index) and most of the time this is the only way it is used.
