DiagonalVectorType | m_diagonal |
Represents a diagonal matrix with its storage.
_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. |
