mathhelp(topic1 [, topic2 ...] [,usage:T] [,scrollback:T])
mathhelp(topic, subtopic:Subtopics), CHARACTER scalar or vector
mathhelp(topic1:Subtopics1 [,topic2:Subtopics2 ...])
mathhelp(key:Key), CHARACTER scalar Key
mathhelp(index:T [,scrollback:T])

Keywords: general, matrix algebra
mathhelp(Topic1 [, Topic2, ...]) prints help on topics Topic1, Topic2,
... related to macros in file math.mac.  The help is taken from file

mathhelp(Topic1 [, Topic2, ...] , usage:T) prints usage information
related to these macros.

mathhelp(index:T) or simply mathhelp() prints an index of the topics
available using mathhelp().  Alternatively, help(index:"math") does the
same thing.

mathhelp(Topic, subtopic:Subtopic), where Subtopic is a CHARACTER scalar
or vector, prints subtopics of topic Topic.  With subtopic:"?", a list
of subtopics is printed.

mathhelp(Topic1:Subtopics1 [,Topic2:Subtopics2], ...), where Suptopics1
and Subtopics2 are CHARACTER scalars or vectors, prints the specified
subtopics.  You can't use any other keywords with this usage.

In all the first 4 of these usages, you can also include help() keyword
phrase 'scrollback:T' as an argument to mathhelp().  In windowed
versions, this directs the output/command window will be automatically
scrolled back to the start of the help output.

mathhelp(key:key) where key is a quoted string or CHARACTER scalar lists
all topics cross referenced under Key.  mathhelp(key:"?") prints a list
of available cross reference keys for topics in the file.

mathhelp() is implemented as a predefined macro.

See help() for information on direct use of help() to retrieve
information from math.mac.
