pltSig for Matlab version 14Sep23
pltSig (sometimes called plt for short) is a toolbox with an identity
crises since it will be of interest to these three classes of users:
- pltSig is a signal processing toolbox for those users interested in
spectral analysis, z-plane analysis, analog and digital filter design, fft window design, and other
signal processing, engineering, and mathematical topics.
- pltSig includes many programs, but the plt plotting function is the soul of
the toolbox since every application and demo program in the toolbox uses it. If you do a lot of data
exploration, or create plots for presentation or publication you will soon find that the plt function
is essential to your work and far surpases the native Matlab plotting functions (plot and plotyy).
plt offers a consistent and flexible command line interface, all explained in a single well written help
file with examples for every important option. No longer will you have to hunt for obscure handle graphics
commands scattered throughout the Matlab documentation. The advantages of the plt function are too numerous
to list here, but include:
- Improved zooming, panning and cursor controls and support of subplots.
- Automatically generated legend that is also used for toggling traces on/off.
- Interactive editing of trace properties, colors, and annotations.
- Mouse or keyboard driven data editing
- If you design graphical user interfaces as part of your work, your main interest in this toolbox may be
for its collection of pseudo objects. A pseudo object is a combination of
standard Matlab objects designed to simplify the process of creating your GUI designs. At any point
during the design process you can easily use your mouse to adjust the size and position of these pseudo
objects (as well as the traditional Matlab objects). Each application and demo program in the toolbox
(37 in total) will serve as an example of how to use these new objects to enhance your own designs.
To install pltSig you should first get the toolbox from the Mathworks' file exchange, however as a
backup, it is also possible to download the toolbox from the links below:
Here are two additional files that will not appear on file exchange since binary executable files are not allowed there:
- Download the windows executable for the Matlab Preprocessor here: (MPP.EXE ver 1.7).
- If you want to use any of the applications in this toolbox, but you don't have Matlab you can run the compiled
version by downloading pltSigEXE.zip (22 Mbytes).
This is a Windows application, so you can't run it on a Unix-based operating system (unless perhaps you have a
Windows emulator). Simply unzip the archive to a folder of your choosing and double click on the pltSig.exe file
to start the application. Click on the white help button for more information.
