Involute Spline Dimensions

Vis5d is intended as a central repository for enhanced versions and development work on Vis5d, a free OpenGL-based volumetric visualization program for scientific datasets in 3 dimensions. Some of the main enhancements in Vis5d include: - autoconf/automake build process: building Vis5d can now...

lvhues is an applet that shows an image changing its hue continuously. It displays an image in all possible colors, changing them periodically. You will find convenient to set the applet dimensions equal to the image dimensions.To use this applet you need to put in your web site both lvhues.class...

Modeless windows, a feature introduced in IE5, presents a window that stays active/visible on the user's screen until explicitly dismissed.A good way to display "announcements" or other content that demand attention. All other browsers will show a regular popup window instead. //Modeless window...

Baseline Fit each column in "x".There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput.Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated...

When drawing financial time series from various markets, one usually needs to make some adjustments before evaluating the series. One of the major concerns is that due to different national holidays or working days across countries, the dates happen to be not synchronized. Clearly this could make...
