Matrix.identity constructor
Creates a matrix of size
* size
dimension, where all the main
diagonal elements are equal to 1, the rest of the elements are 0
import 'package:ml_linalg/matrix.dart';
void main() {
final matrix = Matrix.identity(5);
print(matrix);
}
The output:
Matrix 5 x 5:
(1.0, 0.0, 0.0, 0.0, 0.0)
(0.0, 1.0, 0.0, 0.0, 0.0)
(0.0, 0.0, 1.0, 0.0, 0.0)
(0.0, 0.0, 0.0, 1.0, 0.0)
(0.0, 0.0, 0.0, 0.0, 1.0)
