The Eigen3 library

Collaboration diagram for The Eigen3 library:

Modules
	Cholesky module
	This module provides two variants of the Cholesky decomposition for selfadjoint (hermitian) matrices.
	Core module
	This is the main module of Eigen providing dense matrix and vector support (both fixed and dynamic size) with all the features corresponding to a BLAS library and much more...
	Flags
	These are the possible bits which can be OR'ed to constitute the flags of a matrix or expression.
	Enumerations
	Various enumerations used in Eigen.
	Global matrix typedefs
	Eigen defines several typedef shortcuts for most common matrix and vector types.
	Global array typedefs
	Eigen defines several typedef shortcuts for most common 1D and 2D array types.
	Eigenvalues module
	This module mainly provides various eigenvalue solvers.
	Geometry module
	This module provides support for:
	Householder module
	This module provides Householder transformations.
	Jacobi module
	This module provides Jacobi and Givens rotations.
	LU module
	This module includes LU decomposition and related notions such as matrix inversion and determinant.
	QR module
	This module provides various QR decompositions This module also provides some MatrixBase methods, including:
	Sparse module
	See the Sparse tutorial.
	SVD module
	This module provides SVD decomposition for (currently) real matrices.
