Hello, I want to make 4 plots in one according to below:
R=8.3145;
n=1;
V=linspace(1,10,1000);
T=[100,200,300,400];
for i=1:4
P(i)=n*R*T(i)./ V;
hold on;
plot(V,P(i))
end
hold off;
I am getting the error above. If I do :
P=n*R*T(1)./V;
plot(V,P)
it's ok!I don't understand why the error.
Thank you!

In your line
P(i)=n*R*T(i)./ V;
your n and R and T(i) are scalars, but your V is a vector, so the result is a vector. You are trying to store the vector into a scalar location P(i)

[Tmat, Vmat] = meshgrid(T, V);
P = n .* R .* Tmat ./ Vmat;
plot(V, P)
You might need
plot(V, P')
instead.
