## Synopsis

Jacobi is a comprehensive library for computations involving matrices for

Java programmers. The goal of this project is to provide easy to use matrix 

library with complex computational logic at the fingertip of Java developers.

## Code Example

```java

  Matrix matrix = Matrices.of(new double[][]{ {3.0, 2.0, -1.0}, {2.0, -2.0, 4.0}, {-1.0, 0.5, -1.0} });

  Matrix y = Matrices.of(new double[][]{ {1.0}, {-2.0}, {-2.0} });

  Matrix x = matrix.ext(Solver.class).exact(y); // load Solver extension and solve for x

```
