Worked on enhancing model order reduction workflows in the pymor/pymor repository, focusing on robust support for multi-input multi-output (MIMO) systems and improving the reliability of the PAAAReductor component. Applied Python and numerical methods to optimize Loewner matrix construction using modified Cauchy matrices, refined interpolation partition handling, and addressed edge cases in post-processing to prevent invalid outputs. Emphasized defensive programming and thorough testing, particularly for high-dimensional data and error handling scenarios. These contributions improved runtime efficiency, numerical accuracy, and stability, resulting in more scalable and dependable model reduction tools for users working with complex control systems and data analysis.
