问题描述
我是C ++的新手,并且习惯于MATLAB.不幸的是,我的矩阵大小对于MATLAB来说太大了,所以我想在C ++中尝试一下.我发现本征库3.3.7可以进行矩阵处理.为此,我需要将矩阵市场文件导入Visual Studio2019.我了解C ++的一些基础知识,并尝试使用loadMarket导入文件.尝试编译后,在MarketIO.h文件中收到30个错误.
I'm new to C++ and used to MATLAB. Unfortunatly my matrix size got too big for MATLAB, so I want to try it in C++.I've found the eigen library 3.3.7 to do matrix manipulations. For this I need to import my matrix market files into Visual Studio 2019. I know some basics in C++ and tried to import my files with loadMarket. After trying to compile it I get like 30 errors in the MarketIO.h file.
这是我正在使用的文件. https://eigen.tuxfamily.org/dox/unsupported/MarketIO_8h_source.html
This is the file I'm using.https://eigen.tuxfamily.org/dox/unsupported/MarketIO_8h_source.html
#include <Eigen/Sparse>
#include <unsupported/Eigen/src/SparseExtra/MarketIO.h>
int main(){
typedef Eigen::SparseMatrix<float, Eigen::RowMajor>SMatrixXf;
SMatrixXf A;
Eigen::loadMarket(A, "B.mtx");
}
推荐答案
您绝不能直接包含来自 unsupported/Eigen/src/...
(或来自 Eigen/src/...
).只需包含相应的父标头即可:
You must never directly include files from unsupported/Eigen/src/...
(or from Eigen/src/...
). Just include the corresponding parent header instead:
#include <unsupported/Eigen/SparseExtra>
