Eigen::DiagonalMatrix
template<typename _Scalar, int SizeAtCompileTime, int MaxSizeAtCompileTime>
class Eigen::DiagonalMatrix< _Scalar, SizeAtCompileTime, MaxSizeAtCompileTime >
Represents a diagonal matrix with its storage.
- Parameters
-
_Scalar the type of coefficients SizeAtCompileTime the dimension of the matrix, or Dynamic MaxSizeAtCompileTime the dimension of the matrix, or Dynamic. This parameter is optional and defaults to SizeAtCompileTime. Most of the time, you do not need to specify it.

Construct a diagonal matrix with fixed size from an arbitrary number of coefficients. [c++11]
There exists C++98 anologue constructors for fixed-size diagonal matrices having 2 or 3 coefficients.
- Warning
- To construct a diagonal matrix of fixed size, the number of values passed to this constructor must match the fixed dimension of
*this.
