This is a small Mathematica package that defines a few graphics functions particularly useful in plotting discrete-time signals. An online User's Guide is available here.
Installation instructions: (1) Create the SignalPlot directory in $TopDirectory\AddOns\Applications or $PreferencesDirectory\AddOns\Applications (substitute the appropriate full paths for the Mathematica symbols $*Directory shown here). (2) Unzip the package contents (including subfolders) into the SignalPlot directory created in Step 1. (3) Rebuild the Help Index (see Help menu item).
RIVA presents a seamless approach to the problem of image acquisition and processing with Mathematica. Real-time image capture is made possible by linking Mathematica with PCVision, a popular line of frame grabbers from Coreco Imaging. RIVA connects the Mathematica FrontEnd to the PCVision frame grabber using J/Link, Java Native Interface, Java and ITEX, a set of high-level APIs that encapsulates the knowledge about Coreco Imaging's hardware. From within a Mathematica notebook the user can grab the entire image or a user selected sub-region for immediate processing with Mathematica and the Digital Image Processing application package.
