Result
Attempts iterations times to
fit a sinusoidal regression
model to Xlistname and
Ylistname using a period
guess, and stores the
regression equation to
regequ.
Solves expression for
variable, given an initial
guess and lower and upper
bounds within which the
solution is sought.
Sorts elements of listname
in ascending order.
Sorts elements of
keylistname in ascending
order, then sorts each
dependlist as a dependent
list.
Sorts elements of listname
in descending order.
