Description: Computes the top-k singular triplets or eigenpairs of large
    sparse and structured matrices: the computation behind principal component
    analysis on big sparse data, spectral embeddings, and low-rank
    approximation. Every result carries a numerical certificate with
    residuals, a backward-error bound, orthogonality loss, and a pass/fail
    flag, and bounds that can only be estimated are reported as such rather
    than passed. Centered, scaled, and composed operators are solved through
    native 'C++' kernels without forming dense matrices. Drop-in replacements
    for the 'RSpectra' interface are included.
