Matrix.fromList constructor

Matrix.fromList(
  1. List<List<double>> source, {
  2. DType dtype = DType.float32,
})

Creates a matrix from a two dimensional list, every nested list is a source for a matrix row.

A simple usage example:

import 'package:ml_linalg/matrix.dart';

void main() {
  final matrix = Matrix.fromList([
    [1, 2, 3, 4, 5],
    [6, 7, 8, 9, 0],
  ]);

  print(matrix);
}

The output:

Matrix 2 x 5:
(1.0, 2.0, 3.0, 4.0, 5.0)
(6.0, 7.0, 8.0, 9.0, 0.0)

Implementation

factory Matrix.fromList(
  List<List<double>> source, {
  DType dtype = DType.float32,
}) {
  switch (dtype) {
    case DType.float32:
      return Float32Matrix.fromList(source);

    case DType.float64:
      return Float64Matrix.fromList(source);

    default:
      throw UnimplementedMatrixException(dtype);
  }
}
