Changes in version 0.1.0 (2026-09-21) - First release. - rpchol(): randomly pivoted Cholesky, in its simple and accelerated (rejection-sampling) forms, with greedy and uniform pivoting as baselines. - trace_est() and diag_est(): the XTrace, XNysTrace and XDiag estimators, with Hutch++ and Girard-Hutchinson for comparison. - nystrom(), nystrom_precond(), effective_dim() and pcg(): randomized Nystrom preconditioning for conjugate gradients, solving many right-hand sides at once. - reml_sketch() and reml_exact(): variance components by average-information REML, with the covariance matrix never formed in the sketched fit. - kernel_matrix() and grm_matrix(): kernel and genomic relationship matrices evaluated only where needed.
