Could someone please explain what is wrong in this simple code

Could someone please explain what is wrong in this simple code

cm=@(x,t) exp((-x^2)/(4*Dt))/2*(pi*Dt)^(1/2);
for Dt=[1/16,1/4,1]
for x=-5:.01:5
    hold on 
plot(x,cm)
end

or

cm=inline('exp((-x^2)/(4*Dt))/2*(pi*Dt)^(1/2)','x','Dt');
for Dt=[1/16,1/4,1]
hold on 
fplot(@(x) cm,[-5,5])
end

it doesn't work either way. tnx

end

Is this what you want?

cm = @(x,Dt) exp((-x.^2)/(4*Dt))/2*(pi*Dt)^(1/2);
Dt = [1/16,1/4,1];
x = -5:.01:5;
for k=1:numel(Dt)
    plot(x,cm(x,Dt(k)))
    hold on
end

yes thanks a lot
