the equivalent matlab code for areg ,absorb in stata

Hi, I am new to Matlab. I want to run a regression for an unbalanced panel data.

In stata the code should be :

areg y a b c c2 b2 b*c  if year <=`q', absorb(ind_year)
( c2= c^2, b2 = b^2)

I am wondering whether any equivalent code to run this regression in matlab.

Thank you.

I don't understand your code at all. If you want to fit a polynomial, use polyfit(). For something more complicated, try fitnlm().
