MATLAB AI Coding Rules

MATLAB coding rules and guidelines for AI coding assistants like Cursor, Windsurf, Claude Code, and GitHub Copilot.

Overview

Rule files for AI coding assistants to generate MATLAB code that follows coding standards.

Available Rules

matlab-coding-standards.md

Comprehensive MATLAB coding standards covering:

• Naming conventions for variables, functions, classes, and properties
• Statement and expression guidelines
• Formatting rules and whitespace conventions
• Function and class authoring best practices
• Error handling patterns

Use this rule when: Writing or reviewing any MATLAB code for standards compliance

live-script-generation.md

Guidelines for generating MATLAB Live Scripts in plain text .m format:

• Plain text Live Script formatting rules
• Section structure and documentation
• Mathematical notation and LaTeX support
• Visualization best practices
• Version control compatibility

Use this rule when: Creating MATLAB Live Scripts that need to be version-controlled or AI-generated

matlab-performance-optimization.md

Performance optimization guidelines for MATLAB development:

• Profiling and benchmarking techniques
• Vectorization and implicit expansion
• Memory management and pre-allocation
• Parallel computing with parfor and parfeval
• App Designer performance optimization
• JIT compiler optimization patterns
• File I/O performance strategies

Use this rule when: Writing performance-critical MATLAB code, optimizing existing code, or building responsive applications

Quick Start

Choose your AI coding tool and follow the appropriate setup instructions:

Cursor

Option 1: Project Rules (Recommended)

1. Create a .cursor/rules directory in your project
2. Copy the rule files you want to use:

   mkdir .cursor/rules
   cp matlab-coding-standards.md .cursor/rules/
   cp live-script-generation.md .cursor/rules/
   cp matlab-performance-optimization.md .cursor/rules/
   

3. Cursor will automatically load these rules for your project

Option 2: Reference with @

In your Cursor chat, reference rules directly:

@matlab-coding-standards.md Write a function to calculate eigenvalues

Option 3: Global Rules

Add to Cursor Settings > General > Rules for AI:

When writing MATLAB code, follow the standards at @matlab-coding-standards.md

Windsurf

Option 1: Workspace Rules

1. Create a .windsurf/rules directory in your workspace
2. Copy the rule files:

   mkdir .windsurf/rules
   cp matlab-coding-standards.md .windsurf/rules/
   cp live-script-generation.md .windsurf/rules/
   cp matlab-performance-optimization.md .windsurf/rules/
   

3. Windsurf will automatically apply these rules to your workspace

Option 2: Global Rules

Add to your global_rules.md:

# MATLAB Development

When working with MATLAB code:
1. Follow naming conventions: lowerCamelCase for functions, UpperCamelCase for classes
2. Use arguments blocks for input validation
3. Limit function inputs to 6 or fewer
4. Use spaces (4 per indent), not tabs
5. Keep lines <= 120 characters

Claude Code

Option 1: Project CLAUDE.md (Recommended)

Create a CLAUDE.md file in your project root:
