Matrix.fromByteData constructor

Matrix.fromByteData(
  1. ByteData data,
  2. int rowCount,
  3. int columnCount, {
  4. DType dtype = DType.float32,
})

Creates a matrix from byte data of rowCount * columnCount elements

A simple usage example:

import 'dart:typed_data';

import 'package:ml_linalg/matrix.dart';

void main() {
  final data = Float32List.fromList([
    1, 2, 3, 4, 5,
    6, 7, 8, 9, 0
  ]).buffer.asByteData();

  final matrix = Matrix.fromByteData(data, 2, 5);

  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.fromByteData(
  ByteData data,
  int rowCount,
  int columnCount, {
  DType dtype = DType.float32,
}) {
  switch (dtype) {
    case DType.float32:
      return Float32Matrix.fromByteData(data, rowCount, columnCount);

    case DType.float64:
      return Float64Matrix.fromByteData(data, rowCount, columnCount);

    default:
      throw UnimplementedMatrixException(dtype);
  }
}
