with Ts=300 , Ti=100 , L=1 , x=0:0.01:L, t=0.5 and a=0.1
I have written the following code but it doesn't work. can sb help me?
clc; clear all
Ts=300;
Ti=100;
a=0.1;
l=1;
Sum=0;
for x=0:0.01:l;
for m=1:1000000
S=((exp(-((m*3.14/l)^2)*0.05))*((1-(-1)^3.14)/(m*3.14))*sin(m*3.14*x));
Sum=Sum+S;
end
T=Ts+2*(Ti-Ts)*Sum;
plot(x,T)
hold on;
end
it should give me a sin like figure but it gives
please help me to find the problem. :((

Looks pretty sinusoidal to me. You've only plotted a very small portion, though. Maybe try letting x run from -5 to 5 to see more of the domain?
Also, I think you can let m be something a lot smaller, and you will still see the limiting behavior well.
I notice in your formula you have (-1)^3.14 in one place where the formula has (-1)^m.
Finally, you can use "pi" in place of 3.14. MATLAB understands what that means.
