Eigen is an efficient open-source C++ library for linear algebra, matrix and vector operations, geometrical transformations, numerical solvers and related algorithms. It has been developed by two great developers namely Benoit Jacob and Gael Guennebaud. It has support for compilers like GCC

Nov 12, 2014 · 1 Answer1. Show activity on this post. Eigen is a library which heavily uses C++ features which are not present in C. As such, it cannot be directly used from a C translation unit. However, you can wrap the parts using Eigen in a separate shared library and expose a C interface. Here is a small example how one could write such a library.

Despite my initial conviction that I was including all relevant compiler flags, in fact I wasn't. I forgot the -fopenmp flag on the C++ ...

Using Block Operations

For example, this argument can be “matrix.csv”. The second input argument is the Eigen matrix object to be saved in the file. The code line 4 is used to specify the format for saving and displaying the data. More details about formatting parameters can be found here. For us, the following input parameters are important.

Dec 11, 2018 · Eigen is versatile. It supports all matrix sizes, from small fixed-size matrices to arbitrarily large dense matrices, and even sparse matrices. It supports all standard numeric types, including std::complex, integers, and is easily extensible to custom numeric types. It supports various matrix decompositions and geometry features.

This table presents a catalog of the coefficient-wise math functions supported by Eigen. In this table, a, b, refer to Array objects or expressions, and m refers to a linear algebra Matrix/Vector object. Standard scalar types are abbreviated as follows: int: i32. float: f. double: d.

The other use is more obscure: to specify that an expression refers to a template function or a type. This regularly trips up programmers that use the Eigen ...

Eigen C++ Matrix Library Tutorial – Saving and Loading Data In and From CSV Files. In this post, we explain how to perform two crucial tasks in the Eigen matrix library. First, we explain how to save a matrix in a Comma Separated Values (CSV) file. Then we explain how to load an Eigen matrix object from a CSV file.
