Description

This program is a GUI that takes as input a transfer function. It decomposes the function into poles, zeros, constants,... and plots the asymptotic approximation of each. Individual terms can be added or deleted from the plot.

For complex roots not working

********* Thank you *********
This is GUI runnig easly , it is important for any engineer

Good.

I'm impressed.

i cannot access bec the following error message.
Error in ==> D:\npa\bode_matlab\matlab_m\BodePlotGui.m
On line 32 ==> fig = openfig(mfilename,'new');
how can i fix it?

Very good Tool for teaching-learning of frequency response

Amazing.
a tool to help out with homework.

Very easy to read, learn and specially for teaching. Congratulations
Updates
15 Nov 2002

Changed URLs, and tested function with v6.5
19 Feb 2003

A file was omitted from zip file (BodePlotGui.fig). This file is in the current zip file.
19 Feb 2003

Previous version was missing a file (BodePlotGui.fig) in zip file. This has been fixed.
21 Feb 2003

Changed REALMAX to realmax, for Linux compatibility.

Added capability to format plots:
   Change line width
   Use optional gray scale
   Add grid to plots
   Display phase as radians

Tweaked colors on GUI
03 Nov 2003

Fixed minor bug with peaking of frequency response when zeta>0.707.

Added button to access my web page that describes the program (and Bode plots in general).
12 Jun 2006

Modified GUI to show asymptotic Bode Plot of entire function as well as its constituent parts.
15 Jun 2006

Last changes introduced some errors for underdamped systems with zeta>0.707. The posted version fixes the problem.
20 Oct 2011

Tweaked rules for making asymptotes.

Made it possible to load transfer functions from workspace.
05 Dec 2011

Fixed a small problem with the figure to make plots fit better.
