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
