I have a C++ module that I use with pybind11 to expose functionality in python. It all works nice, for example I am exposing classes, functions and enumerations from the C++ code, for example: py::class_<MapErrorMsg>(m, "MapErrorMsg") .def(py::init()) .def("SetFilename", &MapErrorMsg::SetFilename) .def("GetFilename", &MapErrorMsg::GetFilename) .def("SetWarnLevel", &MapErrorMsg::SetWarnLevel) .def("Warn", (void (MapErrorMsg::*)(MapErrorState, std::string, std::string)) &MapErrorMsg::Warn, "Warn with a level and two ..

I didn’t do anything or change any settings. When running the following code: from datetime import datetime, timedelta from win10toast import ToastNotifier toast = ToastNotifier() ..

I´ve been trying to numerically calculate the inverse Laplace transforms of functions f(s) involving things like 1/(((a+s^2)^0.5)sinh(b*(a+s^2)^0.5)+cosh(c*(a+s^2)^0.5)). I tried zakian´s method on python, but got an overflow error. So, does anybody know of a program or code(preferably in Python or C++) I can use to find these(having the computational power of an average Laptop)? Source: ..

Consider this little pybind11 wrapper + test: setup.py from pybind11.setup_helpers import Pybind11Extension from pybind11.setup_helpers import build_ext from setuptools import setup setup( name="wrapper", ext_modules=[Pybind11Extension("wrapper", ["wrapper.cpp"])], cmdclass={"build_ext": build_ext}, ) wrapper.cpp #include <pybind11/pybind11.h> #include <pybind11/stl.h> #include <vector> namespace py = pybind11; struct Mesh2d { public: Mesh2d(int numVerts, int numTris) : numVertices(numVerts), numTriangles(numTris) { vertices = new float[numVerts * ..

I have many pictures of a chessboard with a smartphone to calibrate my camera for detecting markers. And then I calibrate my camera with OpenCV: cv::calibrateCamera(objectPoints, imagePoints, cv::Size(viewGray.rows, viewGray.cols), cameraMatrix, distCoeffs, rvecs, tvecs); I calibrate my webcam in my case. But if I want to calibrate an other camera, to do some tests (pose estimation ..
