Dividing Matrices

LFMats goal is to furnish convenient matrix tools for the finite element methods. Actually, theres a lot of libraries for linear algebra on the net, but it seems that its still hard to find flexible and high performance free software for the required procedures (genericity, speed, adaptated...

Algorithm::Munkres is a Perl extension for Munkres solution to classical Assignment problem for square and rectangular matrices. This module extends the solution of Assignment problem for square matrices to rectangular matrices by padding zeros. Thus a rectangular matrix is converted to square...

Bio::NEXUS::MatrixBlock is a Perl module that provides functions for handling blocks that have matrices. SYNOPSIS This module is the super class of Characters, Unaligned, and Distances block classes, and indirectly it is a super-class of Data and History blocks, which are both sub-classes of...

Seldon is a C++ library for linear algebra. Seldon provides matrix and vector structures, and some methods and functions for computations (linear algebra). Seldon is designed to be efficient and convenient, which is notably achieved thanks to template classes. Exception handling and several debug...

This function is a more robust and improved version of my previous submission, matchingpursuit.mThis function computes the projection of a given input vector or matrix onto a "dictionary" of other vectors or matrices using a matching pursuit algorithm. Users may input a vector to be synthesized,...

Let us assume the following MIMO model:Y(k)=HX(k)+Y(k)This file can detect the number of sources, i.e the size of the vector X(k) from the received signal Y(k). The noise is assumed spatially white and the number of receivers must be strictly greater than the number of sources. For more details...
