PV-WAVE On ECN Machines

PV-WAVE Advantage provides fundamental components for rapid application development. It includes an interactive language, reusable objects, portability, and robust graphics and numeric routines.

PV-WAVE Foundation includes an interactive programming language that supports variables and collections of variables, and all the constructs of FORTRAN and C. It provides industry standard I/O, a GUI-based debugger, flexible data management functions, backwards compatibility, and cross-platform compatibility.

PV-WAVE Visual Exploration is an interactive environment for efficient visual data analysis. It consists of multiple high-level application components, called VDA (Visual Data Analysis) Tools, plus the Navigator, a GUI-based intuitive interface to the VDA Tools.

PV-WAVE IMSL Mathematics and PV-WAVE IMSL Statistics provide access to the most frequently used routines in the IMSL FORTRAN Numerical Libraries, as well as extensive online documentation for the routines.

To get started with PV-WAVE at the ECN, there is a "man" page available. To view it, type "man wave" . This article includes most of the "man" page contents.

Online Documentation
Extensive online documentation is available for the components of PV-WAVE. After setting up your PV-WAVE environment (see the next section, Setting Up Your Environment), you may view online copies of the printed manuals by typing, from your shell prompt, "wavedoc" or, from the WAVE> prompt, the command "help, /Documentation" . Also, after your PV-WAVE environment is set up, you may substitute the environment variable $WAVE_DIR whenever the documentation refers to <wavedir> . Note that the documentation is displayed using FrameViewer and you must EXIT the FrameViewer main menu when finished.

Online help is also available after invoking PV-WAVE by typing "help" from the WAVE> prompt, or by selecting HELP from the several PV-WAVE menus and window buttons.

There is an an extensive set of PV-WAVE examples that can be viewed by typing "wave_gallery" from your shell prompt. Read the next section for information on setting up the wave_gallery command.

Setting Up Your Environment
There are several shell scripts available to help set up environment variables and aliases/functions needed when using PV-WAVE and its online documentation. There are two wvsetup shell scripts, one for csh/tcsh users and one for sh/ksh users.

• Type "source /usr/opt/bin/wvsetup" at your shell prompt, if you use csh or tcsh. This will set up the needed environment variables and aliases/functions.
• This command may be added to your .cshrc file. However, this is not recommended if you plan to use both the IMSL and PV-WAVE packages because they use some of the same environment variables but set to different values.
• If you use sh or ksh, typing ". wvsetup.sh" at your shell prompt will do the same thing under a sh/ksh environment. (Note the " . " before "wvsetup.sh". It must be there.)
• This command may be added to your .profile file. However, this is not recommended if you plan to use both the IMSL and PV-WAVE packages because they use some of the same environment variables but set to different values.

Now you have the PV-WAVE environment established that allows you to use the commands wave, wavedbg, wavedoc, and wave_gallery.

Getting Started
After setting up your PV-WAVE environment as explained in the section above, you may invoke PV-WAVE by typing "wave" . The prompt changes to WAVE>. Do not run wave in the background, since you need an active WAVE> prompt for entry of PV-WAVE commands.

From the WAVE> prompt, you may invoke the online help by typing "help" , or invoke the PV-WAVE: Navigator by typing "navigator" . The PV-WAVE: Navigator is a GUI interface to the VDA (Visual Data Analysis) tools. A good introduction to the PV-WAVE: Navigator is presented in the PV-WAVE Tutorial. You may bring up the tutorial alongside the Navigator by typing from the shell prompt "wavedoc" and then selecting PV-WAVE Tutorial from the PV-WAVE Online Documentation menu.

To Exit
To exit PV-WAVE, type "exit" at the WAVE> prompt.

To Print
When printing graphical information from the PV-WAVE: Navigator, you must set up the destination printer by selecting Print Setup... from the File popup menu. Then, in the Printer Setup window, enter the name of the destination printer in the Queue name field. To print to a disk file, select Print to file in the Printer Setup window and enter a filename in the Print to file field. If the file does not print, check for error messages at your WAVE> prompt.
