Can someone please answer this and show the Matlab code? Thanks

Question 4: Temperature distribution in a steel plate a) You are given a square steel plate with all the edges held at a constant temperature 25'C and there three (red) point sources at (O'C placed on the plate. 25 25i 25 25 Use MATLAB and simple numerical methods to cakculate the temperature at each node assuming the plate is at steady state. Please hand a working Matlab-file of the code including the code for the printout requested in i (upload function on AUTonline will be available closer to the due date). i) (4 pas) ii) What sort of boundary condition is this? (2 Pts) i) Use MATLAB to sketch the plate, the source and the isothemfort00, Attach a print out version, with the isotherms numbered. (4 Pts) b) The square steel plate above has all the edges replaced by a non-perfect insulator instead of them being held at 25 C. Answer the below questions if the three red points are held at o'C. Sketch the plate the source and estimate the temperature at any given point on the plate as t oo. Explain how you came to this answer i) 4 Pts) i) What sort of boundary condition is this?
