Hi,
I have my main script with a nested function. p2 is array valued and it is calculated in the main script and nested function as well. To find corresponding p2 array values I use specific time using if condition. My main script is like this:
...
dt =0.0001;
dx=0.001;
ii= (1/dx) +1 *% = 1001;*
for nt=1:30001;
...
for i=1:ii
x(i) = (i-1)*dx;
end
t=(nt-1)*dt; *% TIME !!!*
..
[p2] = p_thick(ii,dx,dt,...); % THIS IS P2. IT IS AN ARRAY VALUED FUNCTION (1*ii)
...
if nt==1001 *% TIME CONDITION*
[p2smallregion] = small_time();
k=2*(t/dx) +1;
figure(1) *% PLOTTING IN TIME 0.1*
plot(x(1:k),p2(1:k),'LineWidth', 1.5);
hold on
plot(x(1:k),p2smallregion(1:k),'r--','LineWidth',1.5)
xlabel('x')
% ylabel('p2s')
..
end
end
And my nested function like this:
function [p2smallregion] = small_time()
dx = 0.001;
ii=(1/dx)+1;
...
...
for nt = 1:30001; % SAME THE NUMBER OF TIME STEPS
t=(nt-1)*dt;
if nt ==1001; % SAME TIME CONDITION GOES HERE
k=2*(t/dx) +1;
for j=1:k
m(j) = (j-1)*dx;
if m(j)<t
p2smallregion(j)=beta1*m(j))+t*2*beta1*alphabar;
else
p2smallregion(j) = t^2*alphabar*m(j);
end
end
end
THE QUESTION IS: As you can see I can plot p2 values from main script and nested function in the same plot in a specific time say=0.1. But How can I plot this in different time values in the same plot? 3D plot with colourbar time range between 0.01 and 0.1 with 11 time values??? Please see attached. I would like to get exactly like attached.

Your question is not clear and the attachment is missing. Can you attach the desired figure? Also, if possible, attach a figure of what you have been able to accomplish so far.
