Reproducible research addendum to Z. Průša. Fast matching pursuit with multi-gabor dictionaries.

This is a reproducible research addendum to the paper

Průša, Balazs, Holighaus: Fast Matching Pursuit with Multi-Gabor Dictionaries preprint

The provided bash scripts will obviously only work on Linux.

Contents

• repr_fig1.m -- Reproduces Figure 1 from the paper. Requires LTFAT.
• setup.sh -- Compiles the matching pursuit decomposition executables from MPTK and LIBLTFAT
• run.sh -- Runs a head-to-head comparison of the two implementations of MP using provided dictionary.
• batch_run_comparison.sh -- Runs a batch comparision as presented in Section V in the paper.

A snippet from the run.sh output:

------------------------Running MPTK's mpd------------------------------
MP DURATION  3.88 s  <---- MP decomposition runtime
 ...
------------------------Running libltfat's mpd--------------------------
INIT DURATION: 114 ms
DURATION: 914 ms <---- MP decomposition runtime
SYN DURATION: 84 ms

Requirements

Required libraries are fftw3, sndfile and pthreads.
