# This is the main index of functions in octave/octave-forge.
# It organizes functions by toolbox and by category within
# each toolbox.  Individual directories may have their own
# INDEX file specifying their own toolboxes, or their own
# categories within the "extra" toolbox.  In general if you
# are adding a function to a directory and it does not already
# have an INDEX file, then you should add it here.  If you
# are adding a new directory, you should probably add a new
# INDEX file.

# An index file has the following format:
#
#  toolbox >> Toolbox name
#  Category Name
#   fn fn fn
#   fn fn fn
#  Category Name
#   fn

# Toolbox and category definitions are on the left, function
# lists are indented.

# If no toolbox is specified, then the categories will go into
# extra.  Only use this if you are contributing a small number
# of specialized functions.

# Lines starting with # are comment lines.

# Some functions may be unavailable in octave or octave-forge.
# If they are not implemented they can be listed as usual
# and they will show up with a description of "not implemented".
# If there is a work around or if the function is available
# elsewhere, you can instead use:
#  fn = workaround description
# This workaround description can use any html markup, but
# keep in mind that it is in a bold-italic environment.  For
# the special case of:
#  fn = use <code>alternate expression</code>
# the bold-italic is automatically suppressed.  You will need
# to use <code> even in references:
#  fn = use <a href="someothersite.html"><code>fn</code></a>
# Sometimes functions are only partially compatible, in which
# case you can list the non-compatible cases separately. To
# refer to another function in the package, use <f>fn</f>.
# E.g.,
#  eig(A,B) = use <f>qz</f>

# Since sites may have many missing functions, you can define
# a macro rather than typing the same link over and again.
#  $id = expansion
# defines the macro id.  You can use $id anywhere in the
# description and it will be expanded.  E.g.,
#  $TSA = see <a href="link_to_spctools">SPC Tools</a>
#  arcov = $TSA <code>armcv</code>
# id is any string of letters, numbers and _.
