Hi Everybody, I need to estimate coefficients of this equation aN^2 + bN. It is standard quadratic function but coefficient c=0. My data is a time series, where:
x= [ 0, 5 ,9, 10,15, 16]y= [715,901, 1139, 1224,1553,1712]F=polyfit(x,y,3)plot(F)
As you can see I am using polyfit, which gives me 3 coefficients: a=1.9029 b=30.1841 c=712.7646. I need c to be 0. Do you know any way to calculate only a and b, setting c as 0? I will much appreciate your help, as i am stuck a bit. Thank you 🙂
