#includeusing namespace Eigen; int main() { Matrix4f mat = Matrix4f::Zero(); return 0; }

#includeThese examples use the Eigen package library, which is a header-only library that can be included in C++ projects. To use Eigen, the header files need to be included and the appropriate namespace needs to be used. The code examples demonstrate how to create and initialize a Matrix4f block object in three different ways.using namespace Eigen; int main() { Matrix4f mat; mat << 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16; return 0; }
