Armadillo Matrix Market

fast_matrix_market provides read/write methods for Armadillo sparse and dense matrices.

Usage

```c++

include

```

c++ arma::Mat<double> A; // or arma::SpMat<double> A;

Not restricted to double matrices. Any type supported by Armadillo that makes sense in Matrix Market is also supported, such as int64_t, float, std::complex<double>, etc.

Reading

```c++ std::ifstream f("input.mtx");

fastmatrixmarket::readmatrixmarket_arma(f, A); ```

Note: Armadillo versions older than 10.5 did not zero-initialize memory. On those versions reading any Matrix Market file into a dense arma::Mat is not supported.

Writing

```c++ std::ofstream f("output.mtx", std::ios_base::binary);

fastmatrixmarket::writematrixmarket_arma(f, A); ```
