I wrote the following code but am stuck on how to Update prcLeastSquareLA, so it does what prcLeastSquare does.

I believe you have to add error estimate information in prcLeastSquareLA but I have tried to no avail.

prcLeastSquareLA:= proc(data,degree)
local vars,y,A,V,k,e,i,j,v,c,1stVars;

vars:= seq(ci, i=0..degree);
y:=unapply(‘+’(seq(ci*t^j, i=0..degree)),t);
for k

Hello,

Can anyone help me with this error in Maple while using prcNewton to find local extrema: 

> prcNewton := proc () 

local ftn, strpt, epsilon, maxlps, i, xn, dftn; 

if 4 < nargs then 

elif nargs < 2 then end if; 

if nargs = 2 then 

epsilon := 1/10000000; 

maxlps := 1000 

elif nargs = 3 then
