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

Are you using the same compiler? Did u install the microsoft visual studio compiler? Every compiler has different setup options

[@neverix_3600]

Silly to reply after 2weeks but, accidently solved it for me so ill mention it, u must not put a space after "-I"
for example:
"-IC:/Libraries/eigen-3.4.0/" works
"-I C:/Libraries/eigen-3.4.0/" does not work

@@neverix_3600 Thank you very much for sharing since other people will most likely encounter these problems. Small typos are usually the ones that are the most difficult to find.

I do have vs code installed in my system. But I don't have developer command prompt.

[@aleksandarhaber]

First, watch this video: 2) How to install and setup VS code:
ruclips.net/video/2KGM3-r8eK8/видео.html
There you will learn that you need a C++ compiler in the VS code. I am using the free Microsoft Visual Studio C++ Compiler that comes with the Microsoft Visual Studio Free Community Edition. After you install the Microsoft Visual Studio, you will see the development environment from where you need to start your VS Code editor.

how can I install eigen c++ in vscode in ubunto?

[@aleksandarhaber]

We will cover that in the future.

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
