Error using surf (line 71) Data dimensions must agree.. How to rectify this error.

tspan = [t_sr t_ss];
y=zeros(2,m);
y0 = [T_amb(1); T_amb(1)];
[t,y] = ode15s(@(t,y) odefcn(t,y,T_amb), tspan, y0);

figure
plot(t,y(:,1),'o',t,y(:,2),'+')
        ylabel('temperature(oC)');
        xlabel('time in decimal(s)');
Tp=y(:,2);      
t1 =linspace(20580,59520,5);
r=linspace(0.0005,0.01,5);
ul = Tp(1);
ur = Tp(48);
m =1;
sol = pdepe(m,@pdex1pde,@pdex1ic,@pdex1bc,t1,r);
T = sol(:,:,1);

surf(r,t,T)
title('Numerical solution computed with 20 mesh points')
xlabel('Radius r')
ylabel('Time t')

There are too many missing parts to run the posted code.

See if this works —

surf(t,r,T)

.
