Maxima Coding Sessions

This folder contains Maxima scripts for daily coding experiments and problem-solving sessions. Maxima is a computer algebra system used for symbolic computation, mathematical modeling, and solving equations.

Setup

  • Maxima is installed at: C:\maxima-5.48.1\bin\maxima.bat
  • To run a script, use the batch file (e.g., run_day1.bat) or execute directly with Maxima.

Organization

Files are organized by day:

  • day1.mac - Introduction to Maxima: basic arithmetic, symbolic expressions, differentiation, integration, equation solving, and function definitions.
  • day2.mac - Comprehensive exploration of Maxima features:
    • Part 1: Budget calculations with state revenue and expenses (education, health, interest), including percentage calculations.
    • Part 2: Implementation of the "rule of three" (rule of proportion) for proportional calculations.
    • Part 3: Per capita and monthly per capita revenue calculations.
    • Part 4: Detailed explanation and examples of Maxima's assignment operators (: for variables vs := for functions).
    • Part 5: Multi-year budget analysis using lists, percentage mapping, budget differences, custom function definition, equation solving, and 2D plotting.

Running Scripts

Using Batch File

  • For day1: Run run_day1.bat to execute day1.mac in batch mode.

Manual Execution

  • Open command prompt in this folder.
  • Run: "C:\maxima-5.48.1\bin\maxima.bat" -b day1.mac

Interactive Mode

  • Run: "C:\maxima-5.48.1\bin\maxima.bat"
  • Then load the script: batch("day1.mac");

Creating New Day Files

Use the new_day.ps1 script in the parent directory to create new day files. It prompts for the folder name (e.g., "Maxima") and creates the next numbered dayN.mac file.

Context for Future Sessions

This workspace is part of a broader "Coding Sessions" project for daily programming challenges. Each day focuses on different concepts or problems, using Maxima for mathematical computations. Day 1 covers basics, while Day 2 appears to involve financial calculations, possibly for a budgeting problem.
