C++调用Armadillo计算库

article/2025/8/20 22:10:06

1. 下载压缩包，解压到目录，比如D:\ALGLIB\armadillo，只保留include文件夹和examples里的lib_win32文件夹即可；

下载地址：Armadillo: C++ library for linear algebra & scientific computinghttp://arma.sourceforge.net/download.html

2. 配置项目

将blas_win32_MT.dll和lapack_win32_MT.dll文件拷贝到exe根目录。

测试代码
