### Eigen: Getting started

Posted: (6 days ago) This is a very short guide on how to get started with Eigen.It has a dual purpose. It serves as a minimal introduction to the Eigen library for people who want to start coding as soon as possible. You can also read this page as the first part of the Tutorial, which explains the library in more detail; in this case you will continue with The Matrix class.

### Eigen: Linear algebra and decompositions

Posted: (4 days ago) Computing inverse and determinant. First of all, make sure that you really want this. While inverse and determinant are fundamental mathematical concepts, in numerical linear algebra they are not as popular as in pure mathematics.Inverse computations are often advantageously replaced by solve() operations, and the determinant is often not a good way of checking if a matrix is invertible.

This module provides Haskell binding for Eigen C++ library. Eigen is versatile.

### c - OpenCV CV::Mat and Eigen::Matrix - Stack Overflow

Posted: (3 days ago) You can map arbitrary matrices between Eigen and OpenCV (without copying data). You have to be aware of two things though: Eigen defaults to column-major storage, OpenCV stores row-major. Therefore, use the Eigen::RowMajor flag when mapping OpenCV data. The OpenCV matrix has to be continuous (i.e. ocvMatrix.isContinuous() needs to be true).
