Here you can download the MATLAB-Toolboxes: Please click on the version-number v-.--» to choose toolbox! For Linear Time-Frequency Analysis Toolbox click »here«. |
You have to login before you can upload M-files or create/edit a toolbox! If you don't have a login, please send a request to harald.schwab@univie.ac.at |

ASKNUML | ZIP-FILE | |

macha11 | Download the two matlab files: Copy them to the folder you want to install the toolbox in (e.g. /home/matlab). Then run setupmacha, this file should take you through the installation and tell you where to extract which files to. After completing the extraction process cd to the directory you put the two downloaded m files into and run startmacha. This sets the correct paths and takes you to the wks11 folder, which is supposed to be the workspace. Repeat this step every time you start matlab to be sure that the correct paths are set and that you have all the necessarry files in the scope. |

IRSATOUR-Irregular_Sampling_Tour | Classical collection (a tour through the irregular sampling problem) of irregular sampling algorithms developed at NuHAG. Comments are welcome. These algorithms correspond to "second generation" algorithms and are not competitive anymore compared to mroe recent ones, but they are a good first introduction to field. |

Andreas_Reuther-Gabor_package | Output of an IAESTE fellowship at NuHAG, collection of Gabor routines (selfcontained) with some Demo's included and MAT-files for routines of length n=144 and n=288 respectively. | ZIP-FILE |

metaplectic_toolbox | provides routines to compute dual gabor window for nonseparable lattices using metaplectic transformations, that is first transforming the whole gabor system to a separable setting, computing dual gabor window there, and then again going back to a nonseparabe setting. It also compares the computing speed with the methods already known (uses P. Sondergaard's toolbox, below). The algorithm is based on a paper of H.G. Feichtinger, M. Hazewinkel, N. Kaiblinger, E. Matusiak and M. Neuhauser: "Metaplectic operators on C^n". |

HSOperFramXXL | Hilbert-Schmidt Operators and Frames - Classification, Best Approximation by Multipliers and Algorithms This package is linked to a paper by Peter Balazs. It includes codes to find the best approximation of matrices by frame and irregular Gabor multipliers. http://www.kfs.oeaw.ac.at/xxl/finiteframes/hilschmidtfram.html Version: 10/2007 |

OMP4NFFT | S. Kunis' and H. Rauhut's Sparse Recovery Toolbox for Random Sampling Implements Orthogonal Matching Pursuit and Basis Pursuit for sparse recovery with the (equispaced) Fourier matrix and non-equispaced Fourier matrix. Uses the FFT and NFFT (non-equispaced fast Fourier transform). For Basis Pursuit the software relies on other Matlab-Packages for l1-minimization. |

Spline-type Spaces | Collection of M-files for the implementation of various algorithms related to spline-type spaces of one or two (discrete) variables (e.g. orthogonal projection onto the spline-type space,... data interpolation, dual spline, etc. | ZIP-FILE |

NUHAG_BASIC_RESTRUCTURED | This toolbox is similar to the NuGAG basis toolbox. Most of the functionalities are same as that of NuHAG basis toolbox. But the codes and files are more structured compared to NuHAG basis toolbox. The work on this toolbox is still in progress. New version will appear as more work on structuring the NuHAG basis toolbox get done. |
