Eigen::DiagonalMatrix< Scalar_, SizeAtCompileTime, MaxSizeAtCompileTime > Class Template Reference

Detailed Description

template<typename Scalar_, int SizeAtCompileTime, int MaxSizeAtCompileTime>
class Eigen::DiagonalMatrix< Scalar_, SizeAtCompileTime, MaxSizeAtCompileTime >

Represents a diagonal matrix with its storage.

Template 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.
