MUSIC and Ptolemy Classic

"MUSIC detects frequencies in a signal by performing an eigen decomposition on the covariance matrix of a data vector y of M samples obtained from the samples of the received signal."

  • Ptlang description of the SDF MUSIC actor
    These two files from ptolemy/src/kernel/ might be helpful in understanding how the ComplexMatrix class works: Matrix.h Matrix.cc

    • Ptolemy Demos

    Ptolemy 0.7.1

    Ptolemy 0.7.1 contains two SDF MUSIC demos in the matrix palette

    The images of the models were generated with 

    cd $PTOLEMY/src/domains/sdf/demo
$PTOLEMY/bin/prfacet -TOFILE /tmp/lossySpeech.ps -N -n -p -x lossySpeech
pstoimg /tmp/lossySpeech.ps
distill /tmp/lossySpeech.ps
    Note that the original models are in color, but due to software aging, when we generated the images in color, the background of each actor was black.
