Building on the BLAS work as part of an internship at Quansight Labs, Pranav Goswami worked to lay the foundations for LAPACK (Linear Algebra Package) support in stdlib in order to provide higher order linear algebra routines for solving systems of linear equations, eigenvalue problems, matrix factorization, and singular value decomposition. Detailed more fully in his post-internship blog post, Pranav sought to establish an approach for testing and documentation of added implementations and to leverage the ideas of BLIS to create LAPACK interfaces which facilitated interfacing with stdlib's ndarrays and thus minimize data movement and storage requirements. While a good chunk of time was spent working out the kinks and iterating on API design, Pranav made significant headway in adding various implementation utilities and nearly 30 commonly used LAPACK routines. Given the enormity of LAPACK (~1700 routines), this work will continue into the foreseeable future, so be on the lookout for more updates in the months ahead!
