Heat transient equation not executing

I want to implement this formula in matlab. But i couldn't. So it'd be great if anyone can help me. Where x&t ranges from 0.1 to 10.

Please show us your attempt.

clc;

close all;

clear all;

T1=300;

Ti = 350;

L = 10;

alpha = 100;

syms n

T = symsum((exp(((-n*pi)/(2*L))*(alpha*t)))*sin((n*pi*x)/(2*L)),n,1,9)

T(x,t) = T1+((4/pi)*(Ti-T1)*T);

The terms in your series do not agree with the formula you posted.

You must decide which one is correct and which one is wrong.

clc;
close all;
clear all;

T1 = 300;
Ti = 350; 
L = 10;
alpha = 100;

syms n t x
T = symsum((exp(((-n*pi)/(2*L))*(alpha*t)))*sin((n*pi*x)/(2*L)),n,1,20);
T = T1+4/pi*(Ti-T1)*T;
T = matlabFunction(T);
x = 0:0.1:L;
t = 0:0.1:1;
[X,TIME] = meshgrid(x,t);
surf(TIME,X,T(TIME,X))

I need Temperature value(T(x,t)). an x y plot is required. Not the graph you plotted

plot(x,T(t,x))

x = L/2;
t = 0:0.001:0.5;
figure(2)
plot(t,T(t,x))
