functions in std.i - h



returns 1 if FILE has history records, 0 if it does not.

    help, topic  
 or help  

Prints DOCUMENT comment from include file in which the variable  
TOPIC was defined, followed by the line number and filename.  
By opening the file with a text editor, you may be able to find  
out more, especially if no DOCUMENT comment was found.  
  help, set_path  
prints the documentation for the set_path function.  
prints the DOCUMENT comment you are reading.  
This copy of Yorick was launched from the directory:  
**** Y_LAUNCH (computed at runtime) ****  
Yorick's "site directory" at this site is:  
**** Y_SITE (computed at runtime) ****  
You can find out a great deal more about Yorick by browsing  
through these directories.  Begin with the site directory,  
and pay careful attention to the subdirectories doc/ (which  
contains documentation relating to Yorick), and i/ and  
contrib/ (which contain many examples of Yorick programs).  
Look for files called README (or something similar) in any  
of these directories -- they are intended to assist browsers.  
The site directory itself contains std.i and graph.i, which  
are worth reading.  
  help, dbexit  
for help on debug mode.  If your prompt is "dbug>" instead of  
">", dbexit will return you to normal mode.  
to quit Yorick.

    list = histinv(hist)  

returns a list whose histogram is HIST, hist = histogram(list),  
that is, hist(1) 1's followed by hist(2) 2's, followed by hist(3)  
3's, and so on.  The total number of elements in the returned  
list is sum(hist).  All values in HIST must be non-negative;  
if sum(hist)==0, histinv returns [].  The input HIST array may  
have any number of dimensions; the result will always be either  
nil or a 1D array.

SEE ALSO: histogram  


 or histogram(list, weight)  

  returns an array hist which counts the number of occurrences of each  
  element of the input index LIST, which must consist of positive  
  integers (1-origin index values into the result array):  
       histogram(list)(i) = number of occurrences of i in LIST  
  A second argument WEIGHT must have the same shape as LIST; the result  
  will be the sum of WEIGHT:  
       histogram(list)(i) = sum of all WEIGHT(j) where LIST(j)==i  
  The result of the single argument call will be of type long; the  
  result of the two argument call will be of type double (WEIGHT is  
  promoted to that type).  The input argument(s) may have any number  
  of dimensions; the result is always 1-D.  
KEYWORD: top=max_list_value  
  By default, the length of the result is max(LIST).  You may  
  specify that the result have a larger length by means of the TOP  
  keyword.  (Elements beyond max(LIST) will be 0, of course.)
