Extracting Data from Script

function [u,data2,x_data]=AdvDiff
m=0;
x=linspace(0,1,10);
t=linspace(0,1,10);
sol = pdepe(m,@AdvDiffpde,@AdvDiffic,@AdvDiffbc,x,t);
% Extract the first solution component as u.
u = sol(:,:,1);
% A surface plot
surf(x,t,u)

xlabel('Distance,x')
ylabel('Time,t')
zlabel('Concentration,C')
% A solution profile

Call the dunctions with output arguments (Make all variable as output arguments, those data you needed in the currect working directory)

Now output aruguments are avalible in workspace, thease variable are avalible outside if the function also

See the function file, if you execute the main code without function file, all varible are avalible in workspace. Suggested tho see the documentation (Matlab Function Declaration) and another way define those variables as global variables, please go through this.

Any issue let me know
