The goal of this interface is that the style and API should feel natural to most Julia programmers (it is "Julian"). In particular, you can use standard sparse matrices together with HYPRE's solvers through this interface.</p><p>The high level interface does not (currently) provide access to all of HYPREs functionality, but it can easily be combined with the low level interface when necessary.</p><hr/><h5 id="Low-level-interface"><a class="docs-heading-anchor" href="#Low-level-interface">Low level interface</a><a id="Low-level-interface-1"></a><a class="docs-heading-anchor-permalink" href="#Low-level-interface" title="Permalink"></a></h5><p>HYPRE.jl also provide a low level interface for interacting with HYPRE. The goal of this interface is to stay close to the HYPRE C API. In fact, this interface is automatically generated based on HYPRE's header files, so this API maps one-to-one with the C API, see <a href="libhypre/#LibHYPRE-C-API">LibHYPRE C API</a> for more details.</p></article><nav class="docs-footer"><a class="docs-footer-nextpage" href="matrix-vector/">Matrix/vector representation »</a><div class="flexbox-break"></div><p class="footer-message">Powered by <a href="https://github.com/JuliaDocs/Documenter.jl">Documenter.jl</a> and the <a href="https://julialang.org/">Julia Programming Language</a>.</p></nav></div><div class="modal" id="documenter-settings"><div class="modal-background"></div><div class="modal-card"><header class="modal-card-head"><p class="modal-card-title">Settings</p><button class="delete"></button></header><section class="modal-card-body"><p><label class="label">Theme</label><div class="select"><select id="documenter-themepicker"><option value="documenter-light">documenter-light</option><option value="documenter-dark">documenter-dark</option></select></div></p><hr/><p>This document was generated with <a href="https://github.com/JuliaDocs/Documenter.jl">Documenter.jl</a> version 0.28.0-DEV on <span class="colophon-date" title="Saturday 28 September 2024 21:55">Saturday 28 September 2024</span>.
