MATLAB computations of boundary conditions. Assume that the plane z = 0 separates medium 1 (z > 0) and medium 2 (z < 0), with relative permittivities . In MATLAB, find the electric field intensity vector in medium 2 near the boundary (for z = 0⁻), E₂, if (a) no free charge exists on the boundary (ρ_s = 0) and (b) there is a surface charge of density ρ_s = 53.12 pC/m² on the boundary.
