FD-based MATLAB code – direct solution. Write the main MATLAB code for the direct finite-difference analysis of a square coaxial cable, Fig.2.4, based on Eq.(2.15) – see the previous MATLAB exercise. Compute and plot the same quantities as in MATLAB Exercise 2.10, and compare the results obtained by the two programs. (ME2_ 12.m on IR)
