[Matrix-SIG] Sigtools 0.40 released
Tue, 23 Feb 1999 18:14:55 -0600 (EST)
I'm announcing the release of Sigtools 0.40 for Python with Numerical
This module provides several general-purpose signal processing functions
which can operate on Numerical Python arrays. These modules provide
core functionality for signal/image/array processing using Numerical
The module currently has four methods:
(1) an N-D convolution filter (blurring, edge-detection, etc.)
(2) an N-D order filter (a median filter is an example of this type)
(3) a linear_filter function that operates on N-D (possibly
non-contiguous) arrays along an arbitrary axis. The linear_filter
implements any linear system with a rational/polynomial transfer function.
(It is just like the filter function in MATLAB).
(4) a Parks-McClellan algorithm for designing optimal FIR filters: This
is just a wrapper around GPL'd code written by Jake Janovetz.
Tarfiles (with a Setup file)
and RPM's are available at
