jSciPy Sample App

This Android application demonstrates the capabilities of the jSciPy library, a Java/Kotlin port of SciPy's signal processing and scientific computing modules.

Features Demonstrated

This app provides interactive examples for the following jSciPy modules:

Spectral Analysis (New)

• Periodogram: Power Spectral Density estimation.
• Spectrogram: Time-frequency analysis.
• 2D FFT: Two-dimensional Fast Fourier Transform.

Filters

• Butterworth Filter: Low-pass, high-pass, band-pass, and band-stop filtering (including zero-phase filtfilt).
• Chebyshev Filters: Type I and Type II filters with ripple/attenuation control.
• Savitzky-Golay Filter: Smoothing and differentiation of data.

Signal Processing

• Find Peaks: Peak detection in signals.
• Resample: Signal resampling using Fourier method.
• Detrend: Removing linear or constant trends.
• FFT: Fast Fourier Transform operations.
• Hilbert Transform: Analytic signal computation.

Math & Interpolation

• RK4 Solver: Solving Ordinary Differential Equations (ODEs).
• Interpolation: Linear and cubic spline interpolation.

Getting Started

1. Clone the repository.
2. Open in Android Studio.
3. Build and Run on an emulator or device.

The app displays a scrollable list of demos, each showing input data and the processed output using jSciPy.

Dependencies

• com.hissain.jscipy:jscipy:3.1.3 (Included in app/libs)
• Jetpack Compose for UI
