plotting a function with different constant values without specifying the variable
显示 更早的评论
Hello, I am trying to plot the Boltzmann Distribution function with different temperatures in the same graph without specifying the variable. Here, the variable of the function is velocity (v), and the others are constant. Please help me with your suggestions.
Thank you in advance
syms f(v)
m = 2.32*10^-26;
kb = 1.38*10^-23;
T = [77 293 393 1273 2273];
for i = i:length(T)
f = sqrt(m/(2*pi*kb*T(i)))*exp(-1*m*v^2/(2*kb*T(i)));
end
ezplot(f)

I have no idea what range of values ‘v’ is supposed to have here, however ezsurf (or fsurf) may be appropriate —
syms v T
m = 2.32E-26;
kb = 1.38E-23;
Tv = [77 293 393 1273 2273];
% for i = i:length(T)
f(T,v) = sqrt(m/(2*pi*kb*T))*exp(-1*m*v^2/(2*kb*T));
% end
figure
ezsurf(f,[Tv(1) Tv(end) 0 1000])
Experiment to get different results.

O.K.
That was not obvious.
syms v T
m = 2.32E-26;
kb = 1.38E-23;
Tv = [77 293 393 1273 2273];
% for i = i:length(T)
f(v,T) = sqrt(m/(2*pi*kb*T))*exp(-1*m*v^2/(2*kb*T));
% end
NrSp = numel(Tv);
figure
for k = 1:NrSp
subplot(NrSp,1,k)
ezplot(f(v,Tv(k)),[0 500])
grid
title(sprintf('T = %4d',Tv(k)))
% ylim([0 2])
end
Experiment to get different results.
