<a name="index-functions_002c-obsolete"></a>
<a name="index-functions_002c-deprecated"></a>

<p>After being marked as deprecated for two major releases, the following
functions have been removed from Octave.  The third column of the table
shows the version of Octave in which the function was removed.  Prior to
removal, each function in the list was marked as deprecated for at least
two major releases.  All deprecated functions issue warnings explaining
that they will be removed in a future version of Octave, and which
function should be used instead.
</p>
<p>Replacement functions do not always accept precisely the same arguments
as the obsolete function, but should provide equivalent functionality.
