Main MoM matrix, for arbitrary charged body. Write a function matrixA() that computes the matrix [A] in Eq.(1.58) for the method-of-moments analysis of an arbitrary charged metallic body – based on Eq.(1.61). The function is independent of the geometry of the body; rather, it takes as input the previously calculated arrays of surfaces of small patches ΔS_i, i = 1, 2, . . . ,N, and coordinates of their centers (see Fig.1.22, for example). However, the program distinguishes between the following three cases: (i) charged strips (centers along a straight line), (ii) charged plates (centers in one plane), and (iii) charged 3-D objects (centers in 3-D space). This function can then be used in MoM codes for different geometries, as long as the approximation in Eq.(1.61) is used. (matrixA.m on IR)
