MATLAB: How can I get the results in a csv file rather than a figure

heat equationMATLAB

Here is my code:
 L=1;
 t=1;
 k=.001;
 n=11;
 nt=500;
 dx=L/n;
 dt=.002;
 alpha=k*dt/dx^2;
 T0=400*ones(1,n);
 T1=300*ones(1,n);
 T0(1) = 300;
 T0(end) = 300;
 for j=1:nt
    for i=2:n-1
        T1(i)=T0(i)+alpha*(T0(i+1)-2*T0(i)+T0(i-1));
    end
    T0=T1;
 end
 *export(dataset,'file','Trial.csv','Delimiter',',');*
 plot(T1)
I do not want the plot but i want the calculated data exported to a csv file. Can anyone point to my mistake?

EDITED
dlmwrite('Trial.csv',T1,'Delimiter','\n') %exports T1 values as csv file
Likewise you can export all the values in the same csv file
