Knight Contrib Library

The following is a listing of the entire contents of this library for IDL. Click on an individual procedure name to view its header and source code. This listing is a shortened form of the much longer entire library help file. This may be handy for text searchs, be beware that some of these are huge and may take a long time to load or even crash your browser.

List of Routines

• DDREAD This routine reads data in formatted (or unformatted) rows and columns. The name stands for Data Dump Read. By default, comments are skipped and the number of columns is sensed. Many options exist, e.g., selecting rows and columns, reading binary data, and selecting non-default data type and delimiters.
• LEGEND This procedure makes a legend for a plot. The legend can contain a mixture of symbols, linestyles, Hershey characters (vectorfont), and filled polygons (usersym).
• LEGENDTEST Test the legend procedure.
• NBYTES Return the number of bytes in the variable
• NLINES Return the number of lines in a file
• PANELPLOT Plot many sets of variables on one common set of axes
• PPI Make a ppi (plan position indicator) plot, named for the early CRT displays that presented radar data in polar coordinates. Plot is intensity versus range and azimuth. THere are two input forms: for regularly and irregularly gridded data.
• READB Procedure to copy the bits of an array to another IDL variable. Good for internal conversion, but limited in scope. A more general approach would allow other than array input.
• REPLICAS Replicate an array, as replicate.pro does for scalars or structures. Replicas calls replicate if input is a scalar or structure.
• SQUARE Make a square region for plotting with the current device.
• THECOLOR Function to rob a color index from the current color table and set it to the specified color. Then return the index. Options exist for where in the color table the index is chosen. Color names come from the Openwindows colors file, q.v. wrgb.pro.
• TYPEOF Function to return the type of the variable---a shorthand for extracting the type from the array returned by size.
• WEIBULL Function to return the value of the Weibull pdf.
• WRGB Read and display colors from the rgb table---good for choosing X-windows colors and browsing for pleasing hues.
