toaster_linear 1.0.3
Toaster Linear Algebra Library #
Provides rudimentary Linear Algebra Matrices and Functions
Created from templates made available by Stagehand under a BSDstyle license.
Usage #
A simple usage example:
import 'package:toaster_linear/toaster_linear.dart';
void main() {
/// Initialize Matrices using List of Lists
Matrix m1 = Matrix([
[2.0, 4.0],
[6.0, 8.0]
]);
/// Create a 2x3 matrix with default fill value of 0.0
/// [0.0, 0.0, 0.0],
/// [0.0, 0.0, 0.0]
Matrix m2 = Matrix.fill(2, 3);
/// Create a 2x3 matrix with 4.0 as fill
/// [4.0, 4.0, 4.0],
/// [4.0, 4.0, 4.0]
Matrix m3 = Matrix.fill(2, 3, 4.0);
/// You can add matrices of the same size
assert(m3 + m2 == m3);
m3 += m2;
/// You can subtract matrices of the same size
assert(m3  m2 == m3);
m3 = m2;
/// You can multiply matrices
m1 *= m2.transpose();
/// You can scale matrices
m1 *= 3;
/// You can transpose matrices
Matrix m4 = m1.transpose();
print(m3);
print(m4);
}
