Correct eigenvalues computed with quadruple precision by the toolbox. MATLAB is unable to generate accurate results using the double precision. In theory they should coincide: Figure 1. The eigenvalues of the Grcar matrix are displayed in black, and the eigenvalues of the transposed matrix – in red. The two plots below show the eigenvalues of the Grcar matrix computed by MATLAB and by the toolbox, respectively. The main reason is that eigenproblem might be ill- conditioned and hard to compute even when matrix itself is well- conditioned with respect to inversion. Computation of eigenvalues and especially eigenvectors is one of classic problems requiring extended- precision. Eigendecomposition of banded matrices is one of the examples.
In some cases, the speed of quadruple precision computations in toolbox is comparable (or even higher) to double precision routines of MATLAB. We are determined to change the situation by developing high- performance numerical libraries for computations with arbitrary precision, tuned for modern CPU architectures, multi- core parallelism and relying on recent state- of- the- art algorithms.Īll combined makes our toolbox order(s) of magnitude faster compared to famous competitors: Matrix factorization in quadruple precision (5. Their codes were written decades ago using textbook algorithms, without proper optimization nor updates for the latest hardware. Indeed, mainstream numerical software packages are largely responsible for this false perception. There is a common misbelief that arbitrary precision computations are very slow.

GNU/Linux distributions based on Debian macOS / Mac OS X using Macports. Installing everything through software package managers. If you want to install the bleeding-edge or development version of Theano from GitHub, please make sure you are reading the latest version of this page. Toolbox provides a comprehensive library of computational routines covering the following areas: Real and complex numbers, full and sparse matrices, multidimensional arrays.
Quadruple precision computations (compliant with IEEE 7. As a result, existing MATLAB programs can be converted to run with arbitrary precision with minimal changes to source code. The multiprecision numbers and matrices can be seamlessly used in place of the built- in double entities following standard MATLAB syntax rules. The toolbox equips MATLAB with a new multiple precision floating- point numeric type and extensive set of mathematical functions that are capable of computing with arbitrary precision. Multiprecision Computing Toolbox for MATLABThe Multiprecision Computing Toolbox is the MATLAB extension for computing with arbitrary precision.
