FAµST 3.28.4 — New Faust constructors circ, anticirc and toeplitz

In this version you’ll find new Faust “constructors” in matfaust and pyfaust: toeplitz, circ, anticirc. As sparse Fausts these widely used functions in signal processing can spare memory and speed up many use cases.

In the figure below we show the acceleration allowed by the Faust versions of the functions compared to the corresponding full dense matrices built using scipy. The operations evaluated are the Faust-vector and matrix-vector products.

 The figure was produced on a 1.6 Ghz 4-cores CPU.

To reproduct the figure please use the scripts hosted on gitlab.
