[Maxima-discuss] Reg. Polynomial curve fit

[Dr. M K. <rr...@gm...>]

Dear Maxima members,
I am a very newbie to Maxima. Actually I am shifting from mathematica.
Really Maxima is rather intuitive.  I have 'n' number of x, y data sets and
i wish to fit in the form of (n-1) order polynomial equation. y =
a*x^(n-1)+b*x^(n-2) ....and so on. I have tried these codes:
load (lsquares) $
p:matrix([x, y set Data 1], [x, y set Data 2], [x, y set Data 3]...)
lsquares_estimates ( p, [x,y], a*x^(n-1)+b*x^(n-2) ..., [a, b,c,...]);

But it throws syntax error. Kindly give the exact code for the polynomial
fit for numeric data.

*Also please help me to get the code to load a set of numeric data from an
Excel file into Maxima.*

I am so grateful for any help for this.

Thank you

With kind regards
Dr M Kanagasabapathy
