Write the code Using Matlab.

So,retumning to the heat conduction problem,the governing cquation where T is temperature, t is time, x is the distance from the origin, and is the thermal diffusivity. (The thermal diffusivity is the thermal conductivity divided by pc, where p is the density and c is the specific heat.) The boundary condition is T(0,t) b+ Acos(ot) where b is the mean temperature, A is the amplitude, and is the angular frequency. (If you've forgotten, a= 2T!k, where k is the period.) The solution is: T(x,t) = b + A expl-X11- Assume K is 0.7e-06 m2/s Daily temperature fluctuations. Assume an average temperature of 11C (February in Columbia) and an amplitude of 6C. Plot the temperature as a function of depth (x) at 3-hour intervals over a 12-hour day. On a second graph plot the temperature as a function of depth at 3-hour intervals for the following night. (You will choose how much of the solution (in x) you want to show. Show the most important part!) If you are ready, try using the subplot command to make two plots on the same page. Seasonal temperature fluctuations. Assume an average temperature of 19C and an amplitude of 10C. Plot the temperature in July ( April. a. b. 0), October, January, and
