how can i write matlab code ( Heat transfer temperature distribution)

Steady 1-D heat conduction through a copper wire without any heat generation

Boundary conditions : T(0) = 500 K, T(L) = 300 K

Divide the wire in n sections ( n=10)

Plot the temperature distribution

𝑻𝟎 = 𝑻a,

𝑻𝟏 = (𝑻𝟎 + 𝑻𝟐)/2

𝑻𝟐 = (T1 + 𝑻𝟑)/2

𝑻𝒏−𝟏 = (𝑻𝒏−𝟐 + 𝑻𝒏)/2

𝑻𝒏 = 𝑻b
