There's a free version of linfit at
http://www.astro.washington.edu/deutsch-bin/getpro/library37 .html?LINFIT

it's not the same as the IDL version, so you'd need to work it into a
function, and add the keywords that the IDL version makes available

factorial is written (I know, I wrote it :) It should be fully compatible
with the IDL version. It, and a few other library functions live in
the gdl/src/pro directory, in case you haven't found them.

POLY is something like

function poly,x,c

nc=n_elements(c)
p=0*x
for i=nc-1,1L,-1 do p=(p+c[i])*x
p=p+c[0]
return p

end
