Calculatrix #

Calculatrix is a pure Dart computation engine designed for calculator products. It is matrix-first and RPN-first by design: scalar values are represented as 1x1 matrices, so algebraic and stack-based workflows share the same math core.

Status #

• Current line: 2.0.0-dev
• Focus: Stage 2 foundation (matrix core + RPN core)
• Runtime dependencies: none (pure Dart)

Features available now #

• Immutable Matrix type with dimension validation
• Matrix operations: +, -, *, transpose, scalar helpers
• RpnEngine stack with binary operators (add, subtract, multiply)
• Unit tests for matrix and RPN fundamentals

Quick start #

import 'package:calculatrix/calculatrix.dart';

void main() {
	final Matrix a = Matrix(<List<double>>[
		<double>[1, 2],
		<double>[3, 4],
	]);

	final Matrix result = a * Matrix.scalar(2);
	print(result); // Matrix([[2.0, 4.0], [6.0, 8.0]])
}
