SMath studio is a free Mathcad clone developed by Andrey Ivashov.The other Magma on the block is the commercial Magma Computational Algebra System which was updated to version 2.19-7 this month.Version 1.4 Beta of the free GPU accelerated Linear Algebra library, Magma has been released with a nice set of performance enhancements and new functions.Details of version 8.2.3 can be found here. A new minor release of IDL (Interactive Data Language) from Exelis Visual Information Solutions has been released.It’s now at version 13 and has a bucket load of new functions and improvements. Stata is a commercial statistics package that’s been around since 1985.
The sparsity pattern of the output matrix is automatically determined or can be given as input.” The output matrix is constrained to preserve left and right null-spaces exactly. The non-zero entries are chosen to minimize changes to the singular values and singular vectors corresponding to the near null-space. It is an implementation of a matrix sparsification algorithm that takes a general real or complex matrix as input and produces a sparse output matrix of the same size. It is a library that has interfaces in C++, C, and MATLAB. According to the project’s website, “TxSSA is an acronym for Tech-X Corporation Sparse Spectral Approximation. Version 1.0 of TxSSA has been released.Full details of all 1784 routines available at The Numerical Algorithms Group (NAG) have updated the parallel version of their commercial Fortran library to Mark 24.See what’s new by clicking on and follow the ILNumerics team on Twitter to keep right up to date with this product. NET with syntax that’s similar to that of MATLAB. Version 3.0 of ILNumerics was released in June.For details on how to follow Walking Randomly now that Google Reader has died, see this post.
