Thank you! PCL and a few other such libraries use Eigen. Eigen is header-only, has broad CPU support, and has convenient functions for things like SVD, so it's easy to throw it into a low-level C++ program and start crunching data right away.

c++ - Eigen 2D cross product - Stack Overflow

That is the operator, taking a vector as input and returning a matrix, which mimics a cross product with that vector. I know, that it can be easily written, but would like to avoid it: Eigen::Vector3d t = // some vector ; Eigen::Matrix3d t_hat; t_hat << 0, -t (2), t (1), t (2), 0, -t (0), -t (1), t (0), 0; c++. eigen. WebWhen writing a function taking Eigen objects as argument, if you want your function to take as argument any matrix, vector, or expression, just let it take a MatrixBase argument. As an example, here is a function printFirstRow which, given a matrix, vector, or expression x, prints the first row of x. template < typename Derived>.
