# Installation

```sh

  go get -u github.com/wamuir/matrix-market

```

# Usage

```go

  var m market.COO

  file, err := os.Open("sparse.mtx")

  if err != nil {

      log.Fatal(err)

  }

  defer file.Close()

  _, err := m.UnmarshalTextFrom(file)

  if err != nil {

      log.Fatal(err)

  }

  var c *sparse.COO = m.ToCOO()  // github.com/james-bowman/sparse

```
