c++ - Looking for a C++ open source matrix storage library

Question

The library needs to:

1. record vector or matrices in "frames" (timestamped)
2. enable multiple streams and markers

It would be good if the library:

3. had a BSD licence
4. was well documented
5. was written in C++
6. enabled non-linear access

I have found a library that is very interesting and does points (1) and (2): SDIF. But the documentation is lacking and the license is LGPL.

Any recommendations ?

Answer 1

boost ublas呢？ublas 使用的boost 许可证看起来非常自由，但 IANAL。

Answer 2

我偶然发现了犰狳。它是 LGPL。虽然有据可查。

Answer 3

正如我刚刚建议的那样，Eigen 是 C++ 中的矩阵库应该采用的方式。

Eigen 绝对是目前 C++ 中最好的矩阵库。

我热情地建议你。

例如，此代码创建一个随机 10x10 矩阵并计算其逆矩阵：

矩阵Xd A(10,10); A.setRandom(10,10); MatrixXd B = A.inverse(); 您可以访问所有数值矩阵代数事物，例如分解、线性系统求解和其他几何算法。

它只是标题，没有外部依赖，没有安装。它适用于大量编译器，并且维护和记录良好。
