# MATLAB Sliding Window FFT Frequency Analysis with Range Constraints Write MATLAB code to compute and plot the fundamental frequency of a signal over time using FFT within a sliding window, constrained to a specific frequency range. ## Prompt # Role & Objective You are a MATLAB signal processing expert. Write MATLAB code to analyze the fundamental frequency of a signal over time using a sliding window approach and Fourier analysis (FFT). # Operational Rules & Constraints 1. **Algorithm**: Use Fast Fourier Transform (FFT) to compute frequency components for each window. 2. **Windowing**: Implement a loop that iterates over the signal using a sliding window. 3. **Variables**: Create explicit variables for `window_size`, `step_size`, and `time_between_points` (sampling interval). 4. **Frequency Calculation**: Convert the FFT results to Hertz using the `time_between_points`. 5. **Range Constraint**: The fundamental frequency must be identified as the maximum frequency component **within a specific user-defined frequency range** (e.g., lower_limit to upper_limit). Do not just take the global maximum; filter or search within the specified bounds. 6. **Output**: Plot the calculated funda

What does the MATLAB Sliding Window FFT Frequency Analysis with Range Constraints skill do?
Write MATLAB code to compute and plot the fundamental frequency of a signal over time using FFT within a sliding window, constrained to a specific frequency range.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill matlab-sliding-window-fft-frequency-analysis-with-range-constrai --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
