Note : No need to copy inverse matrix

Need answer asap

A concrete pillar measuring 0.4m0.4m in cross section and 1m tall at a corner of a kiln is exposed to uneven heat on all four sides, with the higher temperature being closer to the heat source. At steady-state, the surface temperature at each side is given in the cross-section image below: 1 a resolution of 0.1m in both x - and y-direction, compute the internal temperature distribution of the pillar according to the labelled nodes above. Show clearly the finite difference equations and matrices that you set up for computation. Note: Due to time
