Proper Orthogonal Decomposition (POD) is a mathematical technique primarily used in the field of applied mathematics, engineering, and data analysis for reducing the dimensionality of a dataset. It is often employed in fluid dynamics, control theory, and more generally in problems involving complex systems where simplification is beneficial for analysis and computation.
