I'm going through the Ceres Solver tutorial. Powell's Function Powell's function maps from R^4 -> R^4, so it seems intuitive to define one residual block that takes in a 4-element array x and ...

I'm investigating ways to speed up a large section of C++ code, which has automatic derivatives for computing jacobians. This involves doing some amount of work in the actual residuals, but the maj...

I'm using ceres solver for a project, and when I call the ceres::Solve function, the library starts to output lines such as this one: iterative_schur_complement_solver.cc:88 No parameter blocks le...
