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.

Parameters:
_Scalarthe type of coefficients
SizeAtCompileTimethe dimension of the matrix, or Dynamic
MaxSizeAtCompileTimethe 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.

class DiagonalWrapper

Inherits DiagonalBase< DiagonalMatrix< _Scalar, SizeAtCompileTime, MaxSizeAtCompileTime > >.
