matlab-add-awgn
AWGN & SNR Management
Add white Gaussian noise to signals and convert between SNR definitions (SNR, Eb/No, Es/No, per-subcarrier SNR) for communications system simulations.
When to Use
- Adding noise to a signal in a link simulation
- Converting between Eb/No, Es/No, SNR, or per-subcarrier SNR
- Setting up the correct SNR for a coded, oversampled, or OFDM system
- Obtaining noise variance to pass to a soft-decision demodulator
When NOT to Use
- Configuring fading channels (delay profile, Doppler, antenna arrays)

matlab-agentic-toolkit-setup
Install and configure the MATLAB Agentic Toolkit — detect MATLAB, install the MCP server, register with your AI coding agent, and verify the environment. Supports Claude Code, Codex, GitHub Copilot, Amp, and Gemini CLI.
6matlab-debugging
Diagnose MATLAB errors and unexpected behavior. Breakpoints, workspace inspection, try-catch diagnostics, and common error patterns. Use when debugging functions, tracing errors, inspecting variables, or diagnosing runtime failures.
5matlab-review-code
Review MATLAB code for quality, performance, maintainability, and adherence to MathWorks coding standards. Uses check_matlab_code and matlab_coding_guidelines. Use when reviewing code, checking style, finding code smells, assessing quality, or preparing code for handoff or publication.
5matlab-install-products
Deterministic workflow to download MATLAB Package Manager (mpm) and install MathWorks products from the OS command line with consistent, repeatable behavior. Use when installing MATLAB, Simulink, toolboxes, or support packages via command line, or setting up scripted installations for CI/CD, containers, or fleet provisioning.
