Plotting with full range in the axes

Hi!

I would really like to know how I can make my x-axes with full range, because it stops at 3.

Thank you!

%% Practice 3.6
% Write a script that plots exp(x) and log(x)
% for values of x ranging from 0 to 3.5
clf
x=[0:3.5];
y=exp(x);
plot(x,y,'ro')
hold on
y=log(x);
plot(x,y,'b+')
legend('exp(x)','log(x)')
xlabel('x')
ylabel('exp(x) or log(x)')
title('exp and log on one graph')

x=[0:3.5];

is the same as

x = 0:1:3.5;

which would be x = [0 1 2 3] . That is why your axis stops at 3.

Try

x = linspace(0, 3.5);

It worked! Thank you!

Hopefully one day I will master this - hope is still there!

clf
x=[0:3.5];
y=exp(x);
plot(x,y,'ro')
hold on
y=log(x);
plot(x,y,'b+')
legend('exp(x)','log(x)')
xlabel('x')
ylabel('exp(x) or log(x)')
title('exp and log on one graph')

That appears to be the same code posted originally, except without the original comments. It has the same problem that I described in 2018.
