Question

I want the solution as programm and I need the steps of solution

c floted 4. The following points are given X 1 4 5 6 7 8 10 Y 2 3 11 13 17 22 26 25 37 40 Fit the data with a power and exponential functions, Make a plot of the points an the new functions. . Poyft(P) a- Poly fit e (P use Poly fit

Answer 1

Hello,
       Please find the answer attached below. If the answer has helped you please give a thumbs up rating. Thank you and have a nice day!

NOTE: The polyfit function does not do the exponential fitting of data. It only does a polynomial fitting. For the exponential fitting you need to use the fit function, which is licensed separately.

************** Matlab program *************

%%%%%%%% power function fit
x = 1:10;
y = [2 3 11 13 17 22 26 25 37 40];
n = 5;
p = polyfit(x,y,n)

x1 = linspace(1,10);
y1 = polyval(p,x1);
figure
plot(x,y,'o')
hold on
plot(x1,y1)
hold off

*********** End of program **********

Output:
