Parallel Colt

<h2 id="capabilities">Capabilities</h2>
<p>Parallel Colt has all the capabilities of the original Colt library, with the following additions.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>
</p>
<ul><li>Multithreading</li>
<li>Specialized Matrix data structures</li>
<li>JPlasma
<ul><li>Java port of PLASMA (Parallel Linear Algebra for Scalable Multi-core Architectures).</li></ul></li>
<li>CSparseJ
<ul><li>CSparseJ is a Java port of CSparse (a Concise Sparse matrix package).</li></ul></li>
<li>Netlib-java
<ul><li>Netlib is a collection of mission-critical software components for linear algebra systems (i.e. working with vectors or matrices).</li></ul></li>
<li>Solvers and preconditioners
<ul><li>Mostly adapted from <a href="/facts/Matrix_Toolkit_Java/cUpyB9jE">Matrix Toolkit Java</a></li></ul></li>
<li>Nonlinear Optimization
<ul><li>Java translations of the 1-dimensional minimization routine from the <a href="/facts/MINPACK/8so70MtG">MINPACK</a></li></ul></li>
<li>Matrix reader/writer</li>
<li>All classes that use <a href="/facts/Floating-point_arithmetic/eIckahxe">floating-point arithmetic</a> are implemented in single and double precision.</li>
<li>Parallel quicksort algorithm</li></ul>
<h2 id="usage-example">Usage Example</h2>
<p>Example of Singular Value Decomposition (SVD):
</p>
DenseDoubleAlgebra alg = new DenseDoubleAlgebra();
DenseDoubleSingularValueDecomposition s = alg.svd(matA);

DoubleMatrix2D U = s.getU();
DoubleMatrix2D S = s.getS();
DoubleMatrix2D V = s.getV();

<p>Example of matrix multiplication:
</p>
DenseDoubleAlgebra alg = new DenseDoubleAlgebra();
DoubleMatrix2D result = alg.mult(matA,matB);
