Worked on the mathworks/arrow repository to enhance sparse tensor functionality, focusing on both reliability and usability. Addressed a bug in the SparseCOOTensor class by updating its representation method to accurately display type and shape, improving clarity for users and reducing debugging time. Expanded and integrated comprehensive API documentation for multiple sparse tensor classes, including SparseCOOTensor, SparseCSRMatrix, SparseCSCMatrix, and SparseCSFTensor, to support developer onboarding and future feature development. Utilized Python for both debugging and documentation tasks, ensuring that user-facing outputs are accurate and well-documented. Validated changes through updated tests, reinforcing a robust foundation for ongoing software development.
