In this video, I explain how to install and use the Eigen C++ matrix library. This library is convenient for matrix and linear algebra computations in C++. It is a simple and easy-to-use library that can be used for designing control systems, estimators, and machine learning algorithms.

Thank you man! Migrating from Matlab to C++ and was looking for a way to do more easily matrix operations and this was a savior, the only video that I could find that really helped me...

[VasilevArtem-gu]

thank for such brief and simultaneously useful tutorial

Getting back to C++ to do some AI and graphics work. Excellent content that got me up to speed quickly with Eigen3 library in VS 2022.

thanks for your tutorial, it's very helpful

Thank you so much for this useful video.

NIce tutorial!! Greetings from Paraguay.

[tzgardner]

Great tutorials! I was curious if you have any examples of using the Eigen Map functionality to wrap other matrix types or even complex Objects into an Eigen Matrix to be able to perform Eigen computations?

In line 29, we use MatrixX because the size is unknown but then pass (10, 10) as the dimension?

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

Hi professor! Could teach us how installing and use Eigen library on VsCode editor? (on Windows)
I'm trying do it but I'm not having success

Thanks for making this video, I’m currently learning to implement ML methods and I’ll be using the Eigen library. Your video helped me understand the basics of it and even showed me how to plug it in. I do have one question, I’m pretty sure I’m not 100% sure, the way you set up the Eigen lib means that it’s dynamic library and the linker will handle the connections during the linking stages, correct????

17:45 Why is matrixV.block(0, 0, 2, 2) a 2x2 instead of a 3x3 matrix?

Thank you very much for this intorduction! Is it possible to use Eigen library foк lineal algebra operations on complex matrixes?

[liboyan]

Hello Professor, how to Make Eigen run in parallel? some tutorials?

[wahabfiles]

Good reference to Python and Matlab. I was wondering if Eigen is faster then corresponding Matlab as Matlab also uses c binaries for libraries.

[menaeem]

Is it faster than simple for loop in C++??

[heimojaakonheimo]

We don't need mathlab for anything.
