Eigen Matrix dot is a mathematical operation used to calculate the dot product of two matrices in C++ programming language. This operation can be performed on matrices of any dimensions as long as the number of columns in the first matrix is the same as the number of rows in the second matrix.
Example 1: Here's a simple example that demonstrates how to compute the dot product of two matrices using Eigen library:
#include
int main() { Eigen::Matrix3d A; A << 1, 2, 3, 4, 5, 6, 7, 8, 9;
std::cout << "The dot product of A and B is: \n" << C << std::endl;
return 0; }
In this example, we create two 3x3 matrices (A and B) and compute their dot product using the * operator. The result is stored in a new matrix C and printed to the console.
Example 2: This example shows how to compute the dot product of two different-sized matrices:
std::cout << "The dot product of A and B is: \n" << C << std::endl;
return 0; }
In this example, we create a 2x2 matrix A and a 3x3 matrix B. Despite their different sizes, we can still calculate their dot product using the * operator.
Eigen is an open-source C++ library used for linear algebra operations. It provides various operations like matrix and vector arithmetic, decomposition, solvers etc. Eigen is a popular package for linear algebra computations in C++ programming.
