Hello Everyone!
Here I have a ground plane of certain user inputted dimension. I want to find the distance of each point on the ground plane to the conductor.
The points are defined by u and v with v being along l and u being along b. I need to know how to define the ground plane as a 2 dimensional array.
clc
clear all
clearVars
l = input ( 'Enter the length of GND in m =' );
b = input ( 'Enter the breadth of GND in m =' );
c = input ( 'Enter the height of the cable from the GND in m =' );
h = input ( 'Enter the height of the probe line from the GND in m =' );
u = -b / 2: 0.1: b / 2;
v = -1 / 2: 0.2: 1/2;

Hello GEON G BASTIAN,
You can define the ground plane as a 2-dimensional array by declaring a 2-dimensional variable groundPlane whose each element is a cell array consists of 2 elements (u, v) as show below
l = input ( 'Enter the length of GND in m =' );
b = input ( 'Enter the breadth of GND in m =' );
c = input ( 'Enter the height of the cable from the GND in m =' );
h = input ( 'Enter the height of the probe line from the GND in m =' );
u = -b / 2: 0.1: b / 2;
v = -1 / 2: 0.2: 1/2;
for i = 1:numel(u)
for j = 1:numel(v)
groundPlane{i,j} = [u(i) v(j)];
end
end
