BEFORE WATCHING THIS VIDEO:
(1) MAKE SURE THAT YOU HAVE INSTALLED MICROSOFT VISUAL STUDIO COMMUNITY EDITION (FREE VERSION). BY INSTALLING THIS PROGRAM, YOU WILL ALSO INSTALL THE C++ COMPILER AND THE DEVELOPER COMMAND PROMPT. THIS VIDEO TUTORIAL IS BASED ON THE MICROSOFT VISUAL STUDIO C++ COMPILER.
(2) WATCH THE VIDEO GIVEN BELOW TO PROPERLY INSTALL AND SETUP THE VS CODE EDITOR:
(3) DO NOT SKIP THE STEPS EXPLAINED IN THIS VIDEO. YOU HAVE TO WATCH THE COMPLETE VIDEO IN ORDER TO PROPERLY INSTALL EIGEN LIBRARY.

I added the "-I xxx/eigenPath" in the file <tasks.json> and added eigenPath int the c_cpp_properties.json file [includePath] as the tutorial said, there was an error about "#include <Eigen/Dense>" : 'Eigen/Dense' file not found. I tried many times and the result was the same.

Hi Aleksander. Thanks for nice intro. Have a question pls. How to loop over 2d slices of 3 dimensional matrices. for example in matlab. a = zeros(2, 2, 2), b = ones(2, 2), for i = 1:2 a(:, :, i) = b end. What would be the most efficient and user friendly way to implrment this in C++ using eigen. I tried using Tensor, but I got lost with the approach of using indices and offsets. Thanks in advance
