9 @deffn {Function} implicit_derivative (@var{f},@var{indvarlist},@var{orderlist},@var{depvar})
10 This subroutine computes implicit derivatives of multivariable functions.
11 @var{f} is an array function, the indexes are the derivative degree in the @var{indvarlist} order;
12 @var{indvarlist} is the independent variable list; @var{orderlist} is the order desired; and
13 @var{depvar} is the dependent variable.
15 To use this function write first @code{load("impdiff")}.
