3.Use Eigen for basic algebraic operations on matrices and vectors. The reader should be able to perform addition, multiplication, scalar multiplication, and matrix inversion and transposition. 4.Use Eigen’s built-in functions to create 4x4 transformation matrices. Installing Eigen
The class SparseMatrix is the main sparse matrix representation of Eigen's sparse module; it offers high performance and low memory usage. It implements a more ...
Recall: Eigen provides two kinds of dense objects: mathematical matrices and vectors which are both represented by the template class Matrix, and general 1D and 2D arrays represented by the template class Array: Scalar is the scalar type of the coefficients (e.g., float, double, bool, int, etc.).
Eigen offers matrix/vector arithmetic operations either through overloads of common C++ arithmetic operators such as +, -, *, or through special methods such as dot (), cross (), etc. For the Matrix class (matrices and vectors), operators are only overloaded to support linear-algebraic operations. For example, matrix1 * matrix2 means matrix ...

Get Eigen matrix and vector types for the provided ScalarType. ... Create and fill dense matrices from the Eigen library: EigenMatrix eigen_densemat(6, 5);.
In Eigen, all matrices and vectors are objects of the Matrix template class. Vectors are just a special case of matrices, with either 1 row or 1 column.
The Eigen/Dense header file defines all member functions for the MatrixXd type and related types (see also the table of header files). All classes and functions ...
After reading this page, don't miss our catalogue of dense matrix decompositions. Basic linear solving. The problem: You have a system of equations, that you ...
Packed storage of symmetric matrices is a big enemy of vectorized code, i.e. of speed. Standard practice is to store the relevant N*(N+1)/2 coefficients in the upper or lower triangular part of a full dense NxN matrix and leave the remaining (N-1)*N/2 unreferenced.
