<div class="textblock"><p>The <a href="https://julialang.org">Julia</a> interface of G+Smo is enabled via the <a class="el" href="C_interface.html">C interface</a> of G+Smo.</p>
<h3>Gismo.jl package hierarchy</h3>
<p>The package <a href="https://github.com/gismo/Gismo.jl">Gismo.jl</a> is developed on top of the package <a href="https://github.com/JuliaBinaryWrappers/gismo_jll.jl"><code>gismo_jll</code></a>, which is an automatically generated package using Julia's <a href="https://github.com/JuliaPackaging/BinaryBuilder.jl">BinaryBuilder</a>, using G+Smo's <a href="https://github.com/JuliaPackaging/Yggdrasil/blob/master/G/gismo/build_tarballs.jl"><code>build_tarballs.jl</code> file</a>.</p>
<h3>Calling the C interface in Julia</h3>
<p>Inside Julia, any function from the C interface can be called by the function <code>ccall</code>. For example, the function gsMultiPatch_addPatch is binded to Julia as follows: </p><div class="fragment"><div class="line">function addPatch!(obj::MultiPatch,geom::Geometry)::Nothing</div>
<div class="line"> ccall((:gsMultiPatch_addPatch,libgismo),Cvoid,(Ptr{gsCMultiPatch},Ptr{gsCGeometry},),obj.ptr,geom.ptr)</div>
<div class="line">end</div>
</div><!-- fragment --><dl class="section note"><dt>Note</dt><dd>Since Julia does not natively offer an interface to <a class="elRef" href="http://eigen.tuxfamily.org/dox/namespaceEigen.html">Eigen</a>, the <a class="el" href="classgismo_1_1gsMatrix.html">gsMatrix</a> is binded to Julia using the <code>EigenMatrix</code> types. This type can easily convert to a Julia matrix and can be given to the C interface of G+Smo.</dd></dl>
<h3>Further information and examples</h3>
<p>For further information and examples regarding the Julia interface, we refer to the <a href="https://github.com/gismo/Gismo.jl">Gismo.jl</a> repository, the <a href="julia">Gismo.jl documentation</a>, and the notebooks in the <a href="https://github.com/gismo/try_gismo"><code>try_gismo</code></a> repository. </p>
