want to plot a function

Hi

I want to plot a function

and

the ref plot is

and now I code is

clc

clear

close all;

f=0:10:60;

tk=0.1;

tK=4;

theta0=-0.4;

theta1=0.3;

theta2=13.8/0.2;

for i=(0 0.1 40)

H=(theta0*(tK-tk))+(theta1*(exp(-theta2*tk*i)));

end

plot(f,H)

please help me how do i change my code to fix it?

ThankS

Subscript ‘H’ in the loop, then create ‘f’ tto have the same size as ‘H’ and then plot —

fv = 0:10:60;
tk=0.1;
tK=4;
theta0=-0.4;
theta1=0.3;
theta2=13.8/0.2;
iv = 0 : 0.1 : 40;
for i = 1:numel(iv)
    H(i) = (theta0*(tK-tk))+(theta1*(exp(-theta2*tk*iv(i))));
end
f = linspace(min(fv), max(fv), numel(H));

figure
plot(f,H)
grid
