Growth data of a sunflower plant is given in the following t
Solution
Enter the following MATLAB code:
x = [1 3 5 7 9 11 12 13]
H = [22 51 127 202 227 248 252]
y = [10.5454 3.9804 1 0.2574 0.1189 0.0242 0.0079]
C = 254
P = polyfit (x, log(y), 1);
A = exp(P(2))
B = -P(1)
x1 = [1:1:13];
H1 = C./(1+A*exp(-B*x1));
fprintf(\'The height in week 6 = %6.2f\ \', C/(1+A*exp(-B*6)))
plot (x,H,\'o\')
hold on
plot(x1,H1)
title (\'Height vs Number of weeks\')
xlable(\'t (weeks)\');
ylable(\'Height (cm)\');
Output:
A = 21.1829
B = 0.6058
The height in week 6 = 162.92 cm
