Determinants & Simplex

ARSG Apps

About this app

Determinants & Simplex is the ultimate application for students, engineers, and professionals who need to solve linear algebra and linear programming calculations with speed, precision, and ease.

🚀 Key Features:

1. Advanced Determinant Calculation (N × N):
◦ Dedicated support for square matrices of orders 2x2, 3x3, 4x4, and general dimensions.
◦ Calculation engine based on Gaussian Elimination with Partial Pivoting, ensuring high numerical precision and robust handling of singular matrices.

2. Simplex Method Solver (Linear Programming):
◦ Automated solver for maximization problems of objective functions subject to linear constraints.
◦ Interactive interface for entering objective function coefficients (Z) and constraint inequalities (≤).
◦ Clear display of the optimal value (Zₘₐₓ) and optimal decision variable values (x₁, x₂, \dots).

3. Modern & Adaptive Design (Jetpack Compose & Material 3):
◦ Built with Android's latest UI toolkit (Jetpack Compose and Material 3).
◦ Adaptive Layout: In landscape orientation, the main menu transforms into an elegant 2x2 grid of buttons, eliminating the need for scrolling (zero scrolling).
◦ Custom Theme & Dark Mode: Modern color palette with flawless light and dark mode support for excellent readability.

4. Performance & Reliability:
◦ 100% local on-device processing (offline-first), with zero network latency.
◦ Fully tested with robust unit and UI (E2E) test suites.
