# Toaster Linear Algebra Library #

Provides rudimentary Linear Algebra Matrices and Functions

## 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);
}
