Detailed Description
template<typename _DiagonalVectorType>
class Eigen::DiagonalWrapper< _DiagonalVectorType >
Expression of a diagonal matrix.
- Parameters:
-
_DiagonalVectorType the type of the vector of diagonal coefficients
This class is an expression of a diagonal matrix, but not storing its own vector of diagonal coefficients, instead wrapping an existing vector expression. It is the return type of MatrixBase::asDiagonal() and most of the time this is the only way that it is used.

| Index size | ( | ) | const [inherited] |
- Returns:
- the number of coefficients, which is rows()*cols().
