A Python package for Dynamic Mode Decomposition, providing tools to extract spatiotemporal coherent structures from time-varying datasets.
PyDMD is a Python package for Dynamic Mode Decomposition (DMD), a data-driven technique that extracts spatiotemporal coherent structures from time-varying datasets. It helps researchers and engineers analyze complex systems by decomposing high-dimensional data into interpretable modes that capture underlying dynamics, making it valuable for fields like fluid dynamics, climate science, and engineering.
Researchers, engineers, and data scientists working with time-varying datasets in fields such as fluid dynamics, climate modeling, mechanical engineering, and any domain requiring analysis of spatiotemporal coherent structures.
Developers choose PyDMD for its comprehensive implementation of both standard and advanced DMD variants, seamless integration with the scientific Python stack, and user-friendly API that balances ease of use with deep customization options for specialized analyses.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements multiple DMD variants including Optimized DMD and Physics-informed DMD, allowing users to handle noisy data and large datasets as highlighted in the key features section.
Built on NumPy and SciPy with Matplotlib for visualization, ensuring compatibility with the standard Python data science stack for efficient computations, as stated in the description.
Provides functions like plot_summary for mode reconstruction and energy spectrum analysis, enabling clear insights into system dynamics, demonstrated in the quickstart guide with flow past a cylinder data.
Allows fine-tuning through parameters such as eigenvalue constraints and bagging configurations, supporting both novice and advanced users per the philosophy and quickstart examples.
Advanced methods like Bagging Optimized DMD require multiple trials and large matrix operations, making it resource-heavy for very large datasets despite optimizations.
Effectively using advanced features and interpreting results requires a solid understanding of DMD theory, which might be challenging for newcomers without background in dynamical systems.
Relies on CPU-based NumPy/SciPy operations without built-in GPU acceleration, limiting performance gains for massive computations compared to specialized libraries.
