//! Advanced spectral analysis methods.
//!
//! This module provides:
//!
//! - **Cyclostationary analysis**: Spectral Correlation Function (SCF), cyclic spectral density,
//!   spectral coherence, and cyclic frequency detection via the FFT Accumulation Method (FAM).
//! - **Short-Time Fractional Fourier Transform (STFRFT)**: Fractional Fourier Transform with
//!   time-localization via windowing, using the Ozaktas decomposition algorithm.
//! - **Ambiguity function**: Narrowband and wideband ambiguity functions for radar/sonar
//!   signal analysis, including auto- and cross-ambiguity computations.
