EJML is another linear algebra library which may worth looking: EJML是另一个线性代数库，可能值得一看：

Efficient Java Matrix Library (EJML) is a linear algebra library for manipulating real/complex/dense/sparse matrices. 高效的Java矩阵库（EJML）是用于处理实数/复杂/密集/稀疏矩阵的线性代数库。 Its design goals are; 其设计目标是： 1) to be as computationally and memory efficient as possible for both small and large matrices, and 2) to be accessible to both novices and experts. 1）对于小型和大型矩阵都应尽可能提高计算和存储效率，并且2）新手和专家都可以访问。 These goals are accomplished by dynamically selecting the best algorithms to use at runtime, clean API, and multiple interfaces. 通过动态选择在运行时使用的最佳算法，干净的API和多个接口来实现这些目标。 EJML is free, written in 100% Java and has been released under an Apache v2.0 license. EJML是免费的，使用100％Java编写，并已根据Apache v2.0许可证发行。
