Singular Value Decomposition

A colour (RGB or 3-channel) image may be converted to a quaternion matrix by placing the three colour components into the three quaternionic imaginary parts, leaving the real part zero. The quaternionic singular value decomposition is a technique to decompose the quaternion matrix (representation... Platforms: Matlab

B3MSV Bidirectional Branch and Bound(B3) subset selection using the the Minimum Singular Value (MSV) as the criterion.Consider the following subset selection problem:Given a tall (m x n, m>n) matrix, A, to find n rows of A such that the resulted n x n square submatrix has the largest MSV among...

This program outputs a graphical & numerical image quality measure based on Singular Value Decomposition. For the given images, Blockwise SVD is taken and image quality measure is derived. For details on the implementation, please refer Aleksandr Shnayderman, Alexander Gusev, and Ahmet M.... Platforms: Matlab

This function does the decomposition of a separable nD kernel intoits 1D components, such that a convolution with each of thesecomponents yields the same result as a convolution with the full nDkernel, at a drastic reduction in computational cost.SYNTAX:======= [K1,KN,ERR] =... Platforms: Matlab

zkcm library is a C++ library for multi-precision complex-number matrix calculations. It provides several functionalities including singular value decomposition, tensor product calculation, and tracing-out operations. Platforms: Mac

SSA generates a trayectory matrix from the original series by sliding a window of length L. The trayectory matrix is aproximated using Singular Value Decomposition. The last step reconstructs the series from the aproximated trayectory matrix. The SSA applications include smoothing, filtering, and... Platforms: Matlab

I started with Adam Wyatt's FROG program (on this website) but added to it and edited it beyond recognition. I did, however, subtract one useful feature: This program, as written, is SHG-FROG and GRENOUILLE only!! (Adam Wyatt's program was more general.)--> The program "prepFROG" takes a raw...

PDL::MatrixOps Perl module contains some useful Matrix operations. SYNOPSIS $inv = $a->inv; $det = $a->det; ($lu,$perm,$par) = $a->lu_decomp; $x = lu_backsub($lu,$perm,$b); # solve $a x $x = $b PDL::MatrixOps is PDLs built-in matrix manipulation code. It contains utilities for many... Platforms: *nix

CoNIFER, also knows as Copy Number Inference From Exome Reads is a Python-based tool that uses exome sequencing data to find copy number variants (CNVs) and genotype the copy-number of duplicated genes. As exome capture reactions are subject to strong and systematic capture biases between sample... Platforms: Windows

The CatMV program is a realization of the "Caterpillar"-SSA method for analysis of time series, which may contain missing values. The implemented algorithms result in extraction of additive components of time series such as trends and periodic components, with simultaneous filling in the missing... Platforms: Windows
