# ArduinoEigen
Eigen (a C++ template library for linear algebra) for Arduino
## Eigen Version
- Eigen v3.4.0
## Usage
By using this library, Eigen can be used directly with Arduino. Please refer following official documents for the details of Eigen.
- [Getting Started](https://eigen.tuxfamily.org/dox/GettingStarted.html)
- [Quick reference guide](https://eigen.tuxfamily.org/dox/group__QuickRefPage.html)
- [Sparse matrix manipulations](https://eigen.tuxfamily.org/dox/group__TutorialSparse.html)
### A simple first program
```C++
#include
using Eigen::MatrixXd;
void setup() {
MatrixXd m(2, 2);
m(0, 0) = 3;
m(1, 0) = 2.5;
m(0, 1) = -1;
m(1, 1) = m(1, 0) + m(0, 1);
}
```
### Matrices and vectors (dynamic)
```C++
#include
using namespace Eigen;
void setup() {
MatrixXd m = MatrixXd::Random(3, 3);
m = (m + MatrixXd::Constant(3, 3, 1.2)) * 50;
VectorXd v(3);
v << 1, 2, 3;
VectorXd vo = m * v;
}
```
### Matrices and vectors (static)
```C++
#include
using namespace Eigen;
void setup() {
Matrix3d m = Matrix3d::Random();
m = (m + Matrix3d::Constant(1.2)) * 50;
Vector3d v(1, 2, 3);
Vector3d vo = m * v;
}
```
## Additional Features
### Pseudo Inverse by SVD decomposition
```C++
MatrixXd Jacobi {3, 4};
MatrixXd Jacobi_pinv {4, 3};
Jacobi <<
1, 2, 3, 4,
5, 6, 7, 8,
9, 10, 11, 12;
Jacobi_pinv = Eigen::pseudoInverse(Jacobi);
```
## Note
This library does NOT support following boards because they don't have standard libraries.
- AVR (Uno, Nano, Mega, etc.)
- MEGAAVR (Uno WiFi, Nano Every, etc.)
- SAM (Due)
For such boards, consider using [EigenArduino](https://github.com/vancegroup/EigenArduino).
