Flutter Matrix #

💡What's the Flutter Matrix? #

The matrix class designed for Flutter can also be used in pure Dart, and is also a full-platform alternative to the Matply library. It supports basic matrix operations, linear algebra, probability theory and mathematical statistics, geometric simulation, central difference, etc.

📄Need a local document? #

Flutter Matrix provides a local doc (by markdown, but you need to rename the folder to docs first) folder and a mkdocs-based building module. If you have Python in your environment, change to the same directory as the mkdocs.yml file and run the following command.

pip install mkdocs mkdocs-material pymdown-extensions mkdocs-material-extensions

After successfully installing the above libraries, run the following command again. You will find that you have generated a folder named site. Open the index.html in the folder to browse the online web documents.

mkdocs build

🛎️Attention. #

• Flutter Matrix can run in a pure Dart environment.

✍️Example #

• Use arrange to generate a data matrix with evenly spaced intervals.

import 'package:flutter_matrix/matrix_type.dart';

main() {
  data_format = "%2.1f";
  var mt = Matrix.linspace(
      start: 0,
      end: 10, 
      row: 10, 
      column: 10, 
      keep: true
  );
  mt.visible();
}

• Output.
