Simplex vs SymPy Editor

Do you spend hours solving algebraic matrices by hand, only to have a single sign error ruin your entire Linear Optimization exercise? Understanding the Simplex Algorithm in Operations Research can be frustrating. Current tools are clunky, confusing, and seem like they're from the 90s. DISCOVER SIMPLEX EDUCATIONAL The high-fidelity academic tool designed exclusively for iOS and iPadOS that transforms complex matrices into a fluid, readable, and intuitive visual experience. Perfect for students of Industrial Engineering, Economics, Business Administration, and optimization professionals. WHAT YOU CAN DO: • Dynamic Model Builder: Switch between Maximization (Max Z) and Minimization (Min Z). Enter constraints with operators (≤, ≥, =). • Intelligent Engine: Automatic conversion to Standard Form (injecting slack, surplus, and artificial variables). • Special Case Detection: Identifies unique, multiple (infinite), unbounded, or infeasible solutions without infinite loops. • Local History with SwiftData: Audit your past problems instantly, without re-entering large matrices. CHOOSE HOW TO LEARN: 1. FINAL RESULT MODE (Free): Your executive success card. Visualize the optimal vertex with specific color codes (Green for unique solution, Purple for multiple). 2. STEP-BY-STEP MODE: An interactive learning log that details each iteration and pivot in ultra-readable, single-spaced tables. Access it for free through rewarded ads or unlock it forever. PRO PASS (One-Time Payment - No Subscriptions): Completely remove ads, unlock unlimited offline Step-by-Step Guides, and export your completed exercises as LaTeX code or professional PDFs. Designed following Apple's guidelines to offer you a clean, dark, and fast interface. Pass your course without frustration!

Edit mathematics the way you read it. SymPy editor draws your expression as a real formula, and every piece of it responds to touch: tap a term to select it, type over it, pull it apart, or apply any function from SymPy, the Python computer algebra system that powers it all. The whole CAS runs on your phone. No account, no ads, no tracking, no network: CPython and SymPy are packaged inside the app, everything you type stays on your device, and it all works in airplane mode. EDIT FORMULAS, NOT CODE • Tap any sub-expression (a term, an exponent, a matrix entry) and edit it in place • Type over a selection, or place a caret between terms and insert • Tap an operator to change it: turn + into a product, make an equation, or delete it • Unwrap (cos θ → θ), isolate, delete, copy and paste sub-expressions • The SymPy source line under the formula follows it, and the formula follows the line: edit whichever you prefer ALL OF SYMPY, ONE TAP AWAY • Transform menu: simplify, expand, factor, partial fractions, trig rewriting and more • A menu per type: matrices offer determinant, inverse and transpose; integrals, sums, derivatives and limits offer evaluation; equations swap sides or collect everything on the left • A search box over every SymPy function, asking for the parameters each one needs • An "unevaluated" switch builds Integral(f, x) or Determinant(M) symbolically instead of computing it • A Symbols panel for assumptions (positive, real, integer…) and matrix symbols with their shapes EVERY STEP IS REMEMBERED • The history shows each step and what changed: in red what went, in green what came • Play it as a slideshow, at the speed you choose • Save it as a self-contained web page that works offline, or as a Python script that rebuilds every step with SymPy • Keep several sessions, each with its own history, all on your device FOR STUDENTS, TEACHERS AND SCIENTISTS Complete the square in front of a class, evaluate limits and integrals, manipulate matrices and N-dimensional arrays, and export the derivation when it is done. FREE AND OPEN SOURCE BSD 3-Clause, no strings attached. Worked derivations, the source code and a browser version are at https://upabjojr.github.io/sympy-editor/ — and the same editor runs in Jupyter notebooks (pip install sympy-editor).
